Jobs has told three stories. Each of these three stories is worth appreciating slowly. His first story is about how to link things in life. The second story is: the third story about love and loss is about death. Jobs's wonderful speech, let me  understand: I should take advantage of the youth, take out all the courage to put all the burden and burden down, have nothing, have lost nothing, and fear to lose. Learn to try, take risks, stick to learning and your life goals, make the best of what you want to do, and do not leave any regrets for your life.
