Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
Never complain and never explain.
You never know what motivates you.
It's always too early to quit.
If you're going through hell, keep going.
Who seeks shall find.
Nobody who ever gave his best regretted it.
Nothing is work unless you'd rather be doing something else.
