If you think you can do it, you can.

You never know what motivates you.

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

Quality is not an act, it is a habit.

It's always too early to quit.

Either you run the day or the day runs you.

Expect problems and eat them for breakfast.

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

To know oneself, one should assert oneself.
