The secret of getting ahead is getting started.
Never complain and never explain.
Go for it now. The future is promised to no one.
What you do today can improve all your tomorrows.
Know or listen to those who know.
You never know what motivates you.
Quality is not an act, it is a habit.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
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.
