If I knew on how to become rich I would not be here right now but what I do know is that people who became rich always put hard work and effort first.
The money came later when they proved them selves with hard work and effort.
Richness is a concept that makes you follow it until you get it connected to your name and for that it would probably make you work for it, no rich people in the world got it by just sitting on a chair and smoking, maybe a few did as they have been too lucky but that does not happen to everyone.
Something needs to rich life you are not very big. Home smoke and walk well. And then you can not worry about the future. But if you find a portal to another rich world. That is another matter.
