I think making good or bad decisions is a matter of luck more than anything else.
As you said good looking it is not important. And about intelligence, it is difficult to determine what is in occidental society currently considered as smart.Some stupid useless ideas succeed while other useful ones are forgotten.
I hope you will eventually manage to find people that won´t make you feel alone, whatever you get rich or not. I know that is difficult for you because of your condition, but there is so much people out there, somebody will suit you.
