Put your money in a jar, and launch it to outer space, jk, no really just, hide it under your couch or bed cushion and you'll forget...not for long though because when you start cleaning the house you'll find the money, and you'll have extra money you forgot about! ^.^
limit how much you spend, and only carry that much, plus extra in case of emergency. leave whatever you don't want to spend at home. or if you're saving for something specific, try finding a pic of the item and taping it to your wallet. that should remind you what you're saving for, and help you make a decision on whether to spend it or not.
Being realistic, if you work you may have a car. If you have a car, it costs money for gas, insurance, etc. So you probably cannot save every dime; you have to spend. The key is to first know where your money is going. Keep track of every dollar and find out where it is going. Then create a budget for 1) saving 2) spending and 3) giving. Put those budgeted amounts into separate envelopes and when the money for eating out is gone for the month, find alternatives. Cut out the non-essential, for example, going to movies. That is expensive entertainment, when you can rent for much less and not be tempted to buy popcorn.
You will have to have discipline to say 'no' to a lot of stuff now, in order to have success in the long run. Set a goal and visualize it when you are tempted to blow a few bucks on soda or coffee. That is why you need to first know where it is going. If you buy an expensive drink every day, it adds up. If you just drive around for no reason, it adds up. Believe me, getting out of debt and staying out of debt is great freedom.
