It's always too early to quit.
Without hard work, nothing grows but weeds.
Well done is better than well said.
Who seeks shall find.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Always desire to learn something useful.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
Be kind whenever possible. It is always possible.
A man always has two reasons for doing anything: a good reason and the real reason.
Go as far as you can see when you get there, you'll be able to see farther.
