Be gentle to all and stern with yourself.
Never complain and never explain.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
You never know what motivates you.
Things do not happen. Things are made to happen.
It's always too early to quit.
I can, therefore I am.
Without hard work, nothing grows but weeds.
