First off: greatness is not one-dimensional. Remember that you're comparing everybody against your chosen dimension(s) of excellence. Adding a another dimension is certain to make you a beginner in something again. You're a co-founder now so you might want to consider sales (in the broadest sense.) Secondly, I can guarantee that even in your chosen dimension of excellence there is someone in your town that out-classes you. Try calling the top consultancy in your area, ask them who their best programmer is and buy him dinner. If you can't learn anything from him/her than I'd bet on you being a bad learner. As a general conclusion: if you keep on improving and taking on bigger challenges then at some point you will reach your limits and you will find something you can't succeed at. It took me almost 30 years but when you get there you'll realize a) who exactly is 'better' than you and b) the degree to which you've been slacking all your life before that.
