Well, if you are a wise man then budgeting every money you have for a day, week or even months is an effective one to save money from spending too much. Thriftiness is the key and don't spend much of your money when you have income but spend your money from the leftovers of your savings, in that way you have less spending and you much more to be saved.
The easiest and best way to save money is to budget it wisely so that you can really achieve your goal to save money. On the other hand, do not spend too much money and buy all things that you really needs and not wants. I agree that thriftiness is one the key to save a lot of money. Just do not spend much money and try to find some way to earn extra money.
