You have to be willing to fail to succeed.

As a kid， I spent my summers with my grandparents on their ranch in Texas. I helped fix windmills， vaccinate cattle， and do other chores. We also watched soap operas every afternoon， especially "Days of our Lives." My grandparents belonged to a Caravan Club， a group of Airstream trailer owners who travel together around the U.S. and Canada. And every few summers， we'd join the caravan. We'd hitch up the Airstream trailer to my grandfather's car， and off we'd go， in a line with 300 other Airstream adventurers. I loved and worshipped my grandparents and I really looked forward to these trips. On one particular trip， I was about 10 years old. I was rolling around in the big bench seat in the back of the car. My grandfather was driving. And my grandmother had the passenger seat. She smoked throughout these trips， and I hated the smell.

自由是一种必须每天重新征服的财富。

进步的关键在于坚持和好奇心。

领导力在于因为你的存在而使他人变得更好，并确保这种影响在你离开后依然存在。

领导力是关于做出艰难的决定，而不仅仅是发号施令。

The state, therefore, has not existed from all eternity. There have been societies that did without it, that had no notion of the state or state power. At a certain stage of economic development, which was necessarily bound up with the split of society into classes, the state became a necessity.

The only real prison is fear, and the only real freedom is freedom from fear.
