To know oneself, one should assert oneself.

Either you run the day or the day runs you.

It's always too early to quit.

Be thine own palace, or the world's thy jail.

The secret of getting ahead is getting started.

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

If you think you can do it, you can.

Be gentle to all and stern with yourself.

You never know what motivates you.
