What is the most effective saving money method? 
A technique that is working pretty well for me: Hide the money from myself: I have two bank accounts at different banks. Let's call them A and B. I asked my employer to send my salary into account A. Furthermore I have configured an automatic transfer of money from account A to account B on the first of each month.  I only use account B for all my expenses (rent, credit card, food, etc) and I check its statement quite often. Since the monthly transfer is only 80% of my salary I save money each month in account A. I don't have a credit card attached to the savings account and I almost never look at its statement. Since that money is out of sight, I do not think much about it and I do not think that I could spend it. I know it is a cheap trick, but it works pretty well for me.
