It's always too early to quit.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
You never know what motivates you.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Quality is not an act, it is a habit.
Who seeks shall find.
Happiness comes from... some curious adjustment to life.
In all science, error precedes the truth, and it is better it should go first than last.
