Come up with as many stupid ideas as possible. Then simply start executing these stupid ideas and see if they work.
I suppose history has laughed at many stupid ideas which came to pass. The automobile at one time was a very silly idea. The concept of electricity in our homes was sneered at. Billions of mobile devices interconnected in an invisible web was a stupid idea. Vaccination seemed like a stupid idea. Exploring the stars was a silly idea.
Crazy ideas have transformed our world. The people who came up with these crazy ideas were often chastisized in their lifetimes and are now revered.
So don’t be afraid to dream up stupid ideas. That very silly idea maybe the thing that makes you very wealthy.
