This motto comes from a famous 2005 speech by Steve Jobs . It means that our time is limited, so 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.

this words come from Steve jobs. IT means ‘做事应该带一些紧张感，不要过于松懈，而且要学会听取他人意见，不要自做聪明’。
