If you can dream it, you can do it.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
Expect problems and eat them for breakfast.
It's always too early to quit.
I can, therefore I am.
You never know what motivates you.
Be gentle to all and stern with yourself.
Success breeds success, and failure leads to a sort of fallow period.
