It's always too early to quit.
Never complain and never explain.
Always desire to learn something useful.
Know or listen to those who know.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
Problems are not stop signs, they are guidelines.
After a storm comes a calm.
Either you run the day or the day runs you.
Only the educated are free.
Eagles commonly fly alone. They are crows, daws, and starlings that flock together.
Lay this unto your breast: Old friends, like old swords, still are trusted best.
For the subtlest folly proceeds from the subtlest wisdom.
