Things do not happen. Things are made to happen.
I can, therefore I am.
You never know what motivates you.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
Well done is better than well said.
If you're going through hell, keep going.
It's always too early to quit.
Time goes, you say? Ah, no! alas, time stays, we go.
