"The efficient man is the man who thinks for himself."

"Be unselfish. That is the first and final commandment for those who would be useful and happy in their usefulness. If you think of yourself only, you cannot develop because you are choking the source of development, which is spiritual expansion through thought for others."

"You know that it is only through work that you can achieve anything, either in college or in the world."

"Do not expect the world to look bright, if you habitually wear gray-brown glasses."
