Never complain and never explain.

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

It's always too early to quit.

If you think you can do it, you can.

If you're going through hell, keep going.

If you can dream it, you can do it.

The secret of getting ahead is getting started.

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

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