Interestingly enough, many of the folks I met remarked that they had 1. mentors who helped them get their first, second, nth company off the ground deal with problems, and just plain succeed, and 2. had sought out others doing the same thing. Oh, and these are folks who are the entrepreneurs of the last couple of decades. Guess what, they are the investors and mentors of today. Regarding the feedback of other startup folks, this isn't about going it your own way, far from it, it's about the things that are similar that are a waste of your most value resource - time, the contact you don't have and the intros that can be made, the things you haven't seen that can sink you, but aren't what make your business your business. Why waste time on that crap?
