If you think you can do it, you can.
Always desire to learn something useful.
If you can dream it, you can do it.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Leap, and the net will appear.
If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
You never know what motivates you.
Words of wisdom are spoken by children at least as often as scientists.
