Well it needs to start with budgeting your spending down to necessity only. Spend only what you make and nothing more.
Set up an automatic transfer every month from your bank account to your savings account.
Only buy things on sale.
This may be difficult at first, but it makes you smarter in spending when prices are low and thus you can save a ton of money this way.
Start leaving your credit cards at home and not taking them out with you. This is another great tactic for if you don't have a credit card on hand, you won't be able to use it.
