Never complain and never explain.
Be kind whenever possible. It is always possible.
Only the educated are free.
You never know what motivates you.
If you think you can do it, you can.
It's always too early to quit.
Well done is better than well said.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
If you can dream it, you can do it.
