My husband and I have set a goal to pay off our mortgage within five years. We have a way to go, but keeping this goal in mind has helped us to curb our spending.

I worked out that any amount I put on our mortgage is actually worth five times that amount due to the saving in interest. So when I am thinking about spending $20 on a top, I multiply this amount by five and realise that I do not want to spend $100 on a $20 top! That $20 would be much better invested if it was put into our mortgage.

This super basic mince recipe saves me up to $100 a month on takeaways, thanks to the convenience of having meals already 'half made'.

All you need are:
2kg minced beef
2 cups of red lentils
2 tbsp of vegetable stock powder, or four vegetable stock cubes
1 tsp dried garlic granules
1 dsp dried onion flakes
4 cups of water.

Place all the ingredients into a crockpot and cook on high for two hours, stirring every 30 minutes. It should be thick, aromatic and an unattractive brown colour (don't let this worry you!).

One batch costs just $13 to make and is enough to serve as a base for seven meals for our family (two children and two adults). This saves heaps of money and time too. I usually freeze the mince in margarine tubs, as that seems to be the right amount for one meal for our family.

The meals I made are:

1. Piemaker pies.
   Allow one heaped tablespoon of basic mince per pie. Pour the mince into a small saucepan and add a large spoonful of gravy powder, or a dessertspoon of cornflour and some Vegemite for colour. Heat and stir until thickened. Spoon into pastry cases and cook in the piemaker.

2. Mexican enchiladas.
   I use Mountain Bread or make my own crepes. Lay the bread or crepes in u-shapes in a large baking dish. Mix the mince with an equal amount of tinned or home-made refried beans. Spread the mixture in a sausage shape down the middle of each crepe, fold each side of the crepe over, sprinkle with grated cheese and bake at 180C until the cheese is melted and bubbly. Serve on a bed of rice, topped with natural yoghurt and some salsa.

3. Stuffed capsicums.
   Halve enough capsicums for half or one per person. Spoon the mince straight into the capsicums, top with some mashed potato, pumpkin or sweet potato. Sprinkle with cheese and bake for 40 mins at 180C. Kids love these as the capsicum sweetens when baked.

4. Baked spuds with topping.
   Allow one potato of appropriate size per person. Cook in the microwave according to manufacturer's instructions. Split a cross in the top and pile filling into the opening. Top with natural yoghurt or sour cream and chopped, sauteed bacon. Allow one large tablespoon of filling per potato. Mix the filling with one tin of baked beans and heat in a small saucepan before pouring on to the potatoes.

5. Spring rolls.
   Mix about four tablespoons of mince mixture with a packet of cooked and cooled Two Minute Noodles, some shredded carrot, and 1/2 teaspoon Chinese five spice. Using filo pastry sheets or spring roll wrappers, fold a small handful of filling into each spring roll. Spray liberally with cooking spray and bake at 180C for 20-30 mins.

6. Greek pasta bake (Pastito).
   Heat a container of mince mixture with a 400g tin of peeled tomatoes. Cook enough macaroni for your family and drain well. Mix with the meat mixture and spoon into a large baking dish and top with your favourite white sauce or cheese sauce. Sprinkle on some grated cheese and bake for 40 minutes at 200C.

7. Shepherds pie.
   Add any vegetables of your choice to the mince mixture. Place into a baking dish and top with mashed potato, pumpkin or sweet potato then bake until heated and the potato browns.

I love making scones, and my Mum passed on this wee hint which makes my scones even better.

When the scone recipe calls for milk, use half milk and half water. For some reason, the water makes the scones extra light with the added bonus that it drastically cuts down on your milk usage.

After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.

This hint was a saviour during our last $21 Challenge.

The girls were looking for lunch and complained there was nothing to eat, so I found a large plastic platter and put the following treats on it:

A leftover BBQ sausage, thinly sliced

Two slices of leftover bread, buttered and cut into quarters

A diced kiwifruit

Four strawberries

A small piece of cheese, diced

1/4 tin corn kernels in a lettuce leaf

A muffin, cut in quarters

Four leftover chicken nuggets, cut in halves

A dob of cream cheese with a little corn relish mixed in

Four cucumber slices

Four cherry tomatoes

One Vita Wheat, halved

I gave the girls and myself a saucer each, plus a cocktail fork and everything was eaten and enjoyed. Now we often have 'platter parties' for meals and snacks. A novel way to serve up a meal when you have 'nothing' to eat!

My husband and I have finally found the key to successful saving! The two of us are dreadful savers; while we're good at putting spare change in a jar, we don't know what to do with it once the jar is full! We thought a saving thermometer would be helpful, but wanted something that wouldn't be so obvious when people came over to visit. So we came up with a more subtle brainwave - a jigsaw puzzle!

We bought a jigsaw of what we wanted (a house) and assigned a dollar amount to every piece. Now we 'buy' pieces of the jigsaw puzzle, the money goes in our jar and we bank the money once a month. We even set up challenges for ourselves, such as who 'buys' the most pieces in a month, and we never have to worry about what to buy each other for presents - we buy pieces of the puzzle of course! Once we've completed the puzzle we're going to hang it on the wall - of our new house!

I had been living beyond my means for some time and knew I needed to trim my spending. For the last couple of years, I had been pretty careful with purchases, but was not succeeding in 'cutting my coat according to my cloth'. About eight or nine months ago, I decided I would only spend cold hard cash. I withdrew what I could afford to once a week from the bank and forced myself to make do with that until the following week. What a shock! The first couple of weeks, I was penniless within 24 hours and had long lists of unpurchased 'necessities'. My grocery shopping barely covered the bottom of the trolley. (What a joy when it came to unpacking it!) I discovered I could do without many things and started making all food (including bread) from scratch. Most things tasted better and I enjoyed cooking. I started buying vegetable seedlings and growing them, but have had to trim that back to seeds to supply us with enough. The junk food and alcohol are long gone - the money never makes it that far. I lost weight! But I still wasn't making ends meet, so I had to cut back on contents insurance. The result has been that I am more careful with what I do have and am becoming less concerned about material possessions as I am not acquiring expensive new ones anyway. I had more free time on the weekends as I didn't 'have' to scour the newspaper for the best buys and then rush around putting them on the credit card. However I still needed to trim my expenses, so I had to forgo my medical insurance. I find I am now so much more careful with my lifestyle, diet and exercise and I suspect it is because my subconscious knows that there is no comfortable private hospital or top specialist waiting for me if anything goes wrong.

Petrol is still a thorn in my side and I am very conscious of the percentage of my hard-earned money that is going on harming the environment just to get me to work. Tomorrow I have an interview for a less 'glamorous', but otherwise similar job within walking distance of my home. This would also increase my exercise. So far, the follow-on effects of spending only cash I have in my hand have not ended. But each time I have had to make a tough decision about which 'necessity' to forgo to live within my means, I have discovered that going without is not as bad as I feared and that, oddly enough, I am now healthier, happier, less rushed, more in control of my life and proud of my resourcefulness than I ever was when I had everything I thought I needed.

Slash your washing powder costs by using a tablespoon of washing powder in your machine instead of a scoop. It works just as well! My sister was learning about budgeting and the speaker mentioned that you could get the same wash results by using one flat tablespoon of washing powder as you could if you used a whole scoop. I decided to test this theory and found that even with a full load of washing this proved to be true. I buy a top brand washing powder that costs around $10 per two kilo box and it contains around 148 tablespoons. I used to go through a two kilo box of powder every four to six weeks when I was using a scoop. Generally I do a load of washing every second day, so using one tablespoon per wash, my box of washing powder should now last me nearly 10 months! Just changing this small habit will save me $90 every 10 months on washing powder!

Here is a hint that has saved our family time, money and arguments, not to mention countless wasted scraps of paper. This year we purchased a large diary for family use, labelled it 'Bench-top Notes' and sat it on our bench. In this diary we write notes to each other that in the past, would have been on scrap pieces of paper that would often be missed or mislaid. Anything from appointment reminders, details of missed phone calls, housework or instructions for our teenage boys, or just simple but personal notes to each other such as 'Hi sweetie, have a great day, I love you, see you at 5.30!' and so on! It has tidied up our bench-top, kept us all organised and an added bonus is that we can look back on our entries for confirmation of bills being paid, appointments kept or cancelled with the reason why and smile at the little love notes to and from each other. This diary cost about $12 but it now contains the priceless and lifetime memories of our 'Bench-top Notes'.
