It's always too early to quit.
To be a good loser is to learn how to win.
Know or listen to those who know.
Only the educated are free.
Without hard work, nothing grows but weeds.
Leap, and the net will appear.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
If 50 percent of your career is not filled with failure, you're not really successful.
