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.
If you are really determined to save then you are going to be mindful of your savings. You will really try to save everytime you are going to have the chance and the money to save. You will budget your money to deduct your expenses already for the day or week or month, then save what is going left. And you'll buy only what is needed. Spending less is equal to saving more.
I started with a saving account in a local bank. I depost eur every month in small amounts. Then I buy bitcoins with that money once the total reaches 1000 eur everytime. This is a good way to save money.
