Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Wherever you are - be all there.
If you think you can do it, you can.
To be a good loser is to learn how to win.
You never know what motivates you.
The wise does at once what the fool does at last.
Leap, and the net will appear.
If you're going through hell, keep going.
Know or listen to those who know.
If you know you are on the right track, if you have this inner knowledge, then nobody can turn you off... no matter what they say.
