Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
It's always too early to quit.
The secret of getting ahead is getting started.
I can, therefore I am.
Who seeks shall find.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
If you can dream it, you can do it.
To know oneself, one should assert oneself.
All things by immortal power. Near of far, to each other linked are, that thou canst not stir a flower without troubling of a star.
