By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
If you're going through hell, keep going.
Always desire to learn something useful.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Never complain and never explain.
The secret of getting ahead is getting started.
Well done is better than well said.
Be gentle to all and stern with yourself.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
