How do successful people think? What drives them? Interviews and investigations indicate that there are several keys to success that successful people share.   

First of all, successful people never blame someone or something outside of themselves for their failure to go ahead.They realize that their future lies in their own hands. They understand that they cannot control things in life, such as nature, the past and other people. But in the meantime, they are well aware that they can control their own thoughts and actions. They take responsibility for their life and regard this as one of the most empowering things they can do. Perhaps what most separate successful people from others is that they live life “on purpose”——they are doing what they believe they are put here to do．In their opinion, having a purpose in their life is the most important element that enables them to become fully functioning people．They hold that when they live their life on purpose, their main concern is to do the job right. They love what they do—and it shows. People want to do business with them because of their commitment（投身；奉献）. To live their life on purpose，successful people find a cause they believe in and create a business around it. Besides, they never easily give up.Once they have set up goals in their life, they are willing to do whatever it takes to achieve their goals.Rather than seeing it negative or depressing they use the knowledge to spur themselves on and go after what they want energetically and passionately.
