To know oneself, one should assert oneself.

It's always too early to quit.

Either you run the day or the day runs you.

I can, therefore I am.

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

Never complain and never explain.

Go for it now. The future is promised to no one.

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

Be kind whenever possible. It is always possible.
