Try things the other way around! Let me explain.
The normal guy will do things in this order. Get salary-Buy something,Pay rent,Buy some more , and then try to save.
Just do the opposite, every month you put away what you can as soon as you get your salary and then you can buy something for yourself. , and believe me you can stash away more then you think . "humans adapts"
The most Important thing is to change 2 mindsets. HAVE HAVE HAVE and teach yourself that you are worth to invest in.Maybe a basic thing , but most people honestly dont think they deserve to be rich /feel good/and that money is evil. This is rooted way down in us. But when you get conscious of yourself worth everything changes, and you will be rich in so many ways !
