Charisma and pedigree are over-rated. The problem seems to be that you think you can (or should) be good at everything. Embrace your strengths and find someone who is strong where you're weak. It might take some work to find that person (or team), but if it was easy, everyone would be doing it.

I think it's a bit of an overstatement to say that all founders are charismatic playboys.

People in the industry respect talent and vision more than anything else.
