Know or listen to those who know.

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

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

Either you run the day or the day runs you.

It's always too early to quit.

The most effective way to do it, is to do it.

If you think you can do it, you can.

Wherever you are - be all there.

Well done is better than well said.
