If you think you can do it, you can.
The dog that trots about finds a bone.
After a storm comes a calm.
To be a good loser is to learn how to win.
The most effective way to do it, is to do it.
I can, therefore I am.
Always desire to learn something useful.
To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Without hard work, nothing grows but weeds.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
