That's why there's lots and lots of kinds of hot sauces, and not so many kinds of mustard. Not because it's hard to make interesting mustard - you could make interesting mustard - but people don't, because no one's obsessed with it, and thus no one tells their friends.

Change is not a threat, it's an opportunity. Survival is not the goal, transformative success is.

Learning is not done to you, it is something you choose to do.

Sooner or later, the ones who told you that this isn't the way it's done, the ones who found time to sneer, they will find someone else to hassle. Sooner or later, they stop pointing out how much hubris you've got, how you're not entitled to make a new thing, how you will certainly come to regret your choices. Sooner or later, your work speaks for itself. Outlasting the critics feels like it will take a very long time, but you're more patient than they are.

People don't believe what you tell them. They rarely believe what you show them. They often believe what their friends tell them. They always believe what they tell themselves.
