How to save? Easy, don't spend it. All you need is a little discipline and cut back on the non essentials and its easy. You might find it hard at first but you'll soon get into it. I like to save as much as possible and of course I buy a little bit of coin as an investment too.
But there are basic expenses that you need to spend, and those are mandatory expenses that cannot be postponed to the next month, need to prepare an action plan there where to spend and how much to spend and review it weekly.
