Startups are constantly faced with this struggle of finding the right people who can commit themselves to a proposition that can hurt sometimes. It's not easy fighting - but I guess its this fact that motivates a young team. I've been fortunate enough to work with so many different people, and at every stage I've seen and experienced a different level of this pride. The fact that not everyone can do it is pretty 'bookish'. And it goes against the very instinctive need to be comfortable, safe, and loved.
But as Mr. Godin says - if you really gotta cross the dip, get out of your comfort zone. Cause that's where the cherries grow.
