If you're not saying 'Hell Yeah' about something, say 'No'.

Everyone who became great at something has a similar story: For years, they worked on their craft every day, even if they weren’t in the mood. Always pushing, practicing, working, and improvingYes it takes thousands of hours of practice, but that’s good news! It’s a clear path and it’s under your control.

Care about your customers more than about yourself, and you'll do well.

If you want to be useful, you can always start now. It will be a humble prototype of your grand vision, but you’ll be in the game. Start by teaching someone this week. Starting small puts 100% of your energy into solving real problems for real people.

Obvious to you is amazing to others.

For years, I'd say yes to almost everything, trying to be nice and generous. Feeling obliged to be of service to the world. Maybe also a fear of being forgotten if I don't. But I paid the ultimate price in doing that, because for all those years, I got almost no work done! Some famous authors have written about this: that if they said yes to every request, then they'd never have time to write another book again.

I love that sometimes we need to go to the opposite side of the world to realize assumptions that we didn't even know we had and realize that the opposite may also be true.
