Don't save what is left after spending. But spend what is left after savings.
Wanting to save money is not enough. Anyway, there are a lot of things which didn't come true although you wanted them to.
Saving is a technique
. It's simple. It's just not easy.
If you only come to think about saving after you spend, there is no chance for you to accumulate a considerable fortune, because spending is always irrational.
The way that works is to make plans in advance.
Would it be too much to use 40% of my income to rent an apartment?
Is it really enough to save just 20% every month?
Only by making it clear how much you want to save can you come to know how much you can actually spend.
