The truly successful person doesn't use others, other people use them. 

If you can contribute to others, no matter how small your talent, you too can become successful. The measure of anyone is the number of people that they serve. 

Service to others is the essence of success. No one achieves success without being of service. 

All great men and women became successful because they gave some talent or ability in the service of others. 

Everybody has to be somebody to somebody to be anybody.
