If you think you can do it, you can.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
Only the educated are free.
To know oneself, one should assert oneself.
Never complain and never explain.
Well done is better than well said.
Always desire to learn something useful.
I can, therefore I am.
Don't let your special character and values, the secret that you know and no one else does, the truth - don't let that get swallowed up by the great chewing complacency.
Better be wise by the misfortunes of others than by your own.
