9. Assess The Risk: In 1995, the employer of Warren Buffett's son, Howie, was accused by the FBI of price-fixing. Warren Buffett advised Howie to imagine the worst-and-bast-case scenarios if he stayed with the company. His son quickly realized that the risks of staying far outweighed any potential gains, and he quit the next day. Asking yourself "and then what?" can help you see all of the possible consequences when you're struggling to make a decision -- and can guide you to the smartest choice.

　　10. Know What Success Really Means: Despite his wealth, Warren Buffett does not measure success by dollars. In 2006, he pledged to give away almost his entire fortune to charities, primarily the Bill and Melinda Gates Foundation. He's adamant about not funding monuments to himself -- no Warren Buffett buildings or halls. "I know people who have a lot of money," he says, "and they get testimonial dinners and hospital wings named after them. But the truth is that nobody in the world loves them. When you get to my age, you'll measure your success in life by how many of the people you want to have love you, actually do love you. That's the ultimate test of how you've lived your life."
