I read the other day (HBR?) that 85% of venture-backed startups are dead within 3 years. Say what you will about VC firms, but the companies they fund tend to be a notch above the mean. And they are certainly the types who get (and maybe even ask for) advice. Creating a business (the kind that supports 2+ founders) is HARD.
Thinking your chances are better because you're (by your OWN assessment) smarter, more open to advice, and more hard working than the mean is a dangerous attitude. If you walk into a room and say, "raise your hand if you think you're an above-average driver", pretty much every hand goes up. 50% of them are wrong.
Normally I love Gabriel's posts, but I think this one smacks of Mr. Rogers ("you're special because of who you are").
