If you think you can do it, you can.
The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
Never complain and never explain.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
To him that waits all things reveal themselves, provided that he has the courage not to deny, in the darkness, what he has seen in the light.
