A barrier is of ideas, not of things.

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.

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

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

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

A barrier is of ideas, not of things.

At all times it is better to have a method.
