Well, yes, but let's bear in mind that there's a big confirmation bias there. Were these hundredaires more or less willing to give up than your ordinary founder who ends up with nothing after a few years to a decade at the wheel of a zombie company? Have they never given up on anything at all?

Extraordinary people can fail and regular people can make a lot of dough. I've met with a few billionaires myself and I have to say I didn't find them to be a different class of human. Just luckyer, from good families and with a very good sense of timing. Obviously very good at what they do. But fundamentally not that different from you and I.

I am not by any means calling it an absolute. But the data points tilt in favor of working through the pain and difficulties instead of throwing in the towel at the slightest speed bump.

Consider another point of view then: how many people struck it big on their second, third, fourth startup?

Off the top of my head Uber was Travis' third startup. Does that make him a quitter or a perseverer?

At my age I known plenty of tech entrepreneurs who've been at it for 10 years with no big hits. Statistically some of them will eventually make it. I doubt I'll be able to say sincerely they were the ones with more grit. But I'm sure they themselves will say it for me :)
