What you do today can improve all your tomorrows.
Well done is better than well said.
Expect problems and eat them for breakfast.
If you can dream it, you can do it.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
Wherever you are - be all there.
Things do not happen. Things are made to happen.
Without hard work, nothing grows but weeds.
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.
