Always desire to learn something useful.
The wise does at once what the fool does at last.
You never know what motivates you.
The most effective way to do it, is to do it.
If you're going through hell, keep going.
I can, therefore I am.
To be a good loser is to learn how to win.
The dog that trots about finds a bone.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
Leave the atom alone.
