In my opinion, we need several points: perseverance, wisdom and broad visions. With these, we can make a difference to the world. Why?
For example, US President Roosevelt suffered from polio when his political future was bright, and he can’t stand up normally again. But he did not give up. Under difficult medical conditions, his perseverance led him to serve as the core of the Democratic Party and ascend to the presidency, leaving an indelible legacy in World War II.
The second is Isaac Newton. Faced with phenomena that people are accustomed to, he can think and deduce the underlying principles. like discovering of gravity existence from the apple tree, the essence of optics from light and calculating calculus from a large number of mechanical models. This proved his wisdom and the spirit of brave.
And the third one is one of the greatest entrepreneurs in the world~ Steve Jobs. He can see development opportunities from the technology market. He can unleash his artistic sense to create perfect products.iTunes, iPod, Mac, show his big vision. While enriching people's lives, we also see the rise of an empire.
