Is not about "thick skin" is about entrepreneurs not having the right motives.
From the music book "Effortless Mastery":
"If you weren’t so concerned about your level of playing, you’d hang in for as long as it took. It would be like a hobby.
That’s why this book stresses again and again developing a detachment to what you’re doing while you are doing it.
However, it is so easy to become discouraged.
All you need is one night when you didn’t play what you wanted to hear, and the ego says,
”Screw it! It’s not happening.”
Again and again, this needs to be said:
you probably cannot develop this level of patience if you are vain about your playing!"
Or I can change it for you guys:
"If you weren't so concerned about your personal image and more concern about changing the world,
you'd hang in for as long as it took"
Basically, whoever was "down" that you used as example, is a person who just hasn't found the passion on his project that he claims to have.
Why do people who claim to be "changing the world" go home cry over somebody, being "mean" to them? Is that how easy they get discouraged? Is like if Batman gave up after 1 time the joker made fun of him... Seeing this here, with a bunch of nerds that think they're better than anybody makes me sad. Cause I'm one of you, and I HATE being associated with egotistical people.
