I learned how difficult it is to self-publish a book. It's complex, it's confusing, it's idiosyncratic.

The jewelry business is a very, very tough business - tougher than the computer business. You truly have to understand how to take care of your customers.

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.
