The first good reason to write a book is to add value to people’s lives.
Pursuing your passions makes you more interesting, and interesting people are enchanting.
Luck favors the people who are willing to grind it out.
If you make meaning, you'll make money.
A magnificent cause can overcome a prickly personality, but your ability to enchant people increases if they like you, so you should aspire to both. You’ll know that you’re likeable when you can communicate freely, casually, and comfortably with people.
The root of great companies is make meaning vs. make money.
