Know or listen to those who know.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
It's always too early to quit.
The most effective way to do it, is to do it.
What you do today can improve all your tomorrows.
If you're going through hell, keep going.
Always desire to learn something useful.
After a storm comes a calm.
The secret of getting ahead is getting started.
The one phrase you can use is that success has a thousand fathers, and failure is an orphan.
