Stop consuming. Stop buying into the b/s and only go in for the things in life that really matter. Abandon all of the practices and beliefs that tell you that you need things in order to be happy.
Well if you don't have the money then you can't can you? The only thing that you can do is go out and earn the money so you can then live a wealthy life.
Probably the best answer.
don't allow money to be important to you. live a life void of it, with no intent to gain it. obviously this will require quite a bit of sacrifice and acceptance, but eventually you will probably be happier than those who have it
win a lottery otherwise good luck
