It's always too early to quit.
To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Leap, and the net will appear.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
If you can dream it, you can do it.
The secret of getting ahead is getting started.
Knowledge is never too dear.
