It's always too early to quit.
Who seeks shall find.
The most effective way to do it, is to do it.
Leap, and the net will appear.
If you're going through hell, keep going.
I can, therefore I am.
After a storm comes a calm.
To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Fullness of knowledge always means some understanding of the depths of our ignorance and that is always conducive to humility and reverence.
