I'm a big believer in minimalism. Not materialist minimalism although that's part of it but time and energy minimalism. The body is given only so much energy a day.

Every time you say yes to something you don’t want to do, this will happen: you will resent people, you will do a bad job, you will have less energy for the things you were doing a good job on, you will make less money, and yet another small percentage of your life will be used up, burned up, a smoke signal to the future saying, “I did it again.

Investing is for wealth preservation, not wealth creation, so first you have to make wealth.

Worry will never solve tomorrow's problems. It will only take energy away from today.

Requirements are for people who want to be unhappy. Because it’s your rules or the universe’s rules. The universe is going to win. Every time.

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

Nobody can tell you what to do. No matter what they pay you. No matter what obligations you feel you owe them. Every second defines you. Be who you are, not who anyone else is, or who anyone else wants you to be.
