Every time you get paid or receive money, take like about half of that (or whatever percentage you want) and save it. So that way you'll have money to spend and a good amount of money saved :) Hope this helps!
You can put it in your sock,you can put it in a drawer,you can run it to the bank and then wait till you have more.You can leave it with a friend,you can save it to the end,you can give it to the poor,you can give it to the nice.You can buy a lot of paintings and then resell them twice. You can wear it on your wrist or on your finger while you breathe.You can make it into diamond hearts and wear it on your sleeve. (this answer is a tribute to Dr.Suess)
One way is to stay away from the places that are tempting you to spend needlessly. Mall, video/game store, fast food restaurants. Figure out where your money is going and make a conscious effort to avoid the places you can do without. Once you start saving it will become habit.
