To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

If you can dream it, you can do it.

You never know what motivates you.

It's always too early to quit.

To be a good loser is to learn how to win.

The wise does at once what the fool does at last.

If you're going through hell, keep going.
