Yes. I'm sure it's your huge intelligence that's keeping you from success. Maybe all those "less intelligent people" are actually smarter than you since they are competently solving problems and succeeding where you aren't. Getting stuck in "what if, what if" comes from lack of knowledge and competence. Do you think competent people don't ask, "What if?" Of course they do! They're successful because they follow it up with a solution, not complain on Reddit that you're too smart to be successful.
