Mistakes I've made in the past make me afraid to try new things in the future. I want to be perfect.

Honesty is the fastest way to prevent a mistake from turning into a failure.

Your bosses simply hate you. You created more and more value. They paid you less and less. That's the definition of disdain in my book.

I made so many mistakes in my first successful business I'm almost embarrassed to recount them.

Every successful business, even Google, Facebook, Twitter, started with a combination of manual improvements and friends of the founders using the site.
