Well you know am really bad at managing my money thus what I do is I transfer everything I earn in the bank account of my friend and he won't even let me have a penny from it even if am dying.. though sometimes if I desperately need he does allow me to have a little amount..!! Its more like having a personal finance manager thus if you aren't able to save up yourself I will advise you to ask help from a friend of yours its never a bad option also its better if he is super strict

Also I have planned daily usage like a dollar a day or something like that thus it helps me control whatever I spend.
