You must expect great things of yourself before you can do them.
The way of success is the way of continuous pursuit of knowledge.
A quitter never wins-and-a winner never quits.
Never was anything great achieved without danger.
Our greatest glory is not in never falling, but in rising every time we fall.
If you try and lose then it isn't your fault. But if you don't try and we lose, then it's all your fault.
Orson Scott Card
