正确的爱应该以仰慕为基础，我们应该去爱那些对我们有教育意义的先贤。我懂得这个道理且一辈子都在实践它。
Your time is limited, don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
