Christmas 2009 was the worst I ever had, having just separated from my husband. At almost 50 I found myself homeless with no money. On the 16th of December I found a share accommodation but had to borrow money from friends to pay for my bond and two weeks rent so that I could have a roof over my head. The only job I was able to do to keep me going was as a housekeeper, yet I could hardly pay for the petrol to get to work.

For four weeks, I avoided going to the shops. I am 90% vegetarian so decided to grow all the vegetables I like to eat at my rented home. I collected some seeds, seedlings and cuttings from friends and customers and decided to spend my last $10 for chicken wire to protect my homegrown herbs and vegetables from possums and bush turkeys. I am spending time tending my garden every day and I now have lettuces, beans, cucumbers, cherry tomatoes, herbs and so on for salads and stir fries every day. I even have enough to give some to my friends and customers to thank them for helping me to stand on my own feet and living a healthy life. This week I only spent $16 for organic eggs, milk, a tin of pink salmon and a loaf of bread. These with my homegrown herbs and vegetables will give me a healthy diet for the whole week. I am saving heaps to pay my debts as fast as I can.

At soon-to-be-50 and with no savings, I bought The $21 Challenge book to challenge myself. I am so excited because I spent years of feeding a family of four and now I am alone I have absolute control of what I spend and what I put in my mouth. I feel liberated, I feel young and full of energy. Having less money in 2010 is more enjoyable than my stressful life in 2009!

Imagine getting 14 meals out of a single cooked chicken! It's my biggest food saving and this is how I do it.

Buy a whole chicken (on special of course)! Get a large pot. Place chicken in it and add chunky chopped carrot, onion, celery and mixed herbs (I grow my own so save more money here)!

Boil until the meat is starting to fall off the bone (I have a wood heater so I cook on that, saving gas in winter) Take the meat and vegetables out, reserving the liquid. Serve some of the meat and all the vegetables with mashed potato and white sauce.

With leftover meat, make up some chicken sandwiches and freeze them for quick lunches. Use the rest in curries or whatever other suitable recipes you have.

Back to the liquid. Add a little more water, chop up whatever soup vegetables you have or add lots of lentils, a dash of paprika and salt and slowly simmer to make a few meals of wonderful thick soup. This way, I feed two of us 14 meals out of the one chicken! Not only is it cheap, it is good for you and has helped the purse strings through many tight times over the years.

This simple bill payment system lets you take a holiday from paying bills at Christmas time.

Every time I receive a bill, I pay $10 more than the amount required. For example, if the monthly phone bill is $50, I pay $60. This has worked really well for me, and come December I am able to stop the phone, internet, power and rates payments. I use this money for Christmas gifts, safe in the knowledge that my bills are covered.

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.

I use a simple principle every day, which helps me save money in all areas of my life. I try to reduce my use or consumption of what I normally do by 10%. The rewards are enormous. For example, if you spend $200 a week on groceries, try reducing it by $20 over 52 weeks and straight away you have $1040 extra in your pocket. You and your family won't even notice the difference, as it equates to less than $3.00 a day!

If you apply this principle to all areas of your life - petrol, electricity, phone calls and so on, the savings are huge even though the sacrifice is not even felt. It not only saves money but also the planet by reducing your overall consumption. Once I achieve this 10% reduction, I do it all over again! Every quarter after the electricity bill comes in, I then set myself the 10% goal anew to keep myself on track and to challenge myself to reduce further. This means the $180 grocery bill then reduces by a further $18 a week and so it goes on. I have done this only to a point where it is comfortable and achievable. Because it is baby steps it is easy and fun and not painful! We have saved hundreds, if not thousands, in the last year or two and are not feeling so pressured by the mortgage rate rises. Best of all is that we haven't noticed any difference to our lifestyle.

We had the chance to travel overseas several years ago but had to save $1000 to make it happen. On one income with two small children it seemed impossible. Then I had the brainwave - I didn't have to save $1000, I had to save $1.00 a thousand times! This was so much easier - a generic brand product at the grocery store, a chocolate bar at the petrol station and so on, soon added up and the savings contributed to a great family holiday.

No more dashing to the shops to grab something for dinner when the cupboards are bare! I have discovered a great website to help make the best use of the food you already have in your fridge and pantry cupboard. It is (www.cookingbynumbers.com)

It gives you a list of ingredients and you tick what foodstuffs you have at home on the list, then it comes up with a range of recipes using those ingredients. It is amazing just how much you can make with what is already available to you! It saves on wastage and on buying extra ingredients.

I am 22 years old and on a low income, but am well on the way to saving for my first house! I developed a simple system that keeps my savings goal at the forefront of my mind and encourages the support of those around me.

I've always found it hard to save, but one day I got a big piece of cardboard and wrote 'My House Deposit' at the top. On the right hand side I cut out images of a house, a kitchen and a loungeroom that I would love to own one day. On the left hand side I drew a giant thermometer and on the side wrote the figures $0 to $40 000 ascending, just like on a real thermometer. Whether or not I need $40 000 is irrelevant; I look at this table every day and whenever I save another $500, I colour in with a red crayon up to the amount on the tally. I use hints from Simple Savings, such as making my own lunch every day and not buying clothes if I don't need them and now whenever I make a purchase I think of my house deposit and how much I want it far more than a coffee or new shoes!

An unexpected bonus of having this chart is that I've found my family and boyfriend have become aware of my goals and I get lots of support along the way. This visualisation technique really does wonders, and most importantly you are making a concrete agreement with yourself and you stop losing sight of your goals. I'm already a quarter of the way to reaching mine!

In the spirit of getting organised for May, my tip has to do with letting go of control and coming up with organisational ideas that work with the people you love.

For example, my partner is a wonderful, talented individual who wouldn't know how to put away his clothes even if he was bribed! Clothing was constantly strewn over the floor, on the furniture or stuffed into cupboards and this drove me to distraction on more than one occasion.

Finally it dawned on me that the neatness issue was mine and the organising issue was his, so I discussed what would work best for him. I found out that he would prefer a single place to keep all his clothing, something portable and easy. I went away and, based on what he had told me, set up a system consisting of one large plastic tub on wheels and one small wicker basket. I placed both of these in the bottom of the wardrobe.

Clean clothes now go in the tub and dirty clothes in the basket. When the wicker basket is full, it goes in the wash; I made sure the basket was the same size as a machine load. When washed and dried, the clothes go from the basket back to the tub. Simple!

Now I have a clean bedroom and my partner can always find clean clothes. As a bonus, he's reduced his washing by two-thirds because he is only washing dirty clothes, not a mixture of clean and dirty.

Best of all, there is no longer friction surrounding the tidiness of the bedroom. The idea of working with those you love to create a harmonious living environment, where their needs and ways of doing things are heard and acted on really can have a positive impact, both financially and emotionally.

I make home-made yoghurt in my EasiYo maker for as little as $0.50c per kilo. You don't need to buy the special sachets, all you need is milk powder and a couple of tablespoons of plain yoghurt. I just use 1 and 1/3 cups of milk powder and two heaped tablespoons of yoghurt (saved from the last batch). Easy, cheap and delicious!
