SGLeavitt357's mention about paying yourself first is a good tip. I would recommend reading the book "The Richest Man in Babylon" as it goes into this and more. It is not too long of a book, but if you don't have time to read it you can see the themes summarized in Wikipedia.
One of the themes involves how to cure a lean purse. The first cure is titled: Start thy purse to fattening.
Arkad advises on saving 10% of your annual income to start building up your wealth (or purse): "For every ten coins thou placest within thy purse take out for use but nine. Thy purse will start to fatten at once and its increasing weight will feel good in thy hand and bring satisfaction to thy soul"
I have heard finance gurus in recent years suggest upping the saving to 15% once you are comfortable, though aiming for 10% is great when you are just getting started.
