The successful man doesn't use others, other people use the successful man, for above all the success is of service.

There is nothing wrong in using people. The success never uses people except to their advantage.

You are beginning to see that any man to whom you can do favor is your friend, and that you can do a favor to almost anyone.

At all times it is better to have a method.

You cannot live on other people's promises, but if you promise others enough, you can live on your own.

A barrier is of ideas, not of things.

The successful man doesn't use others, other people use the successful man, for above all the success is of service.
