If you think you can do it, you can.

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

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

If you're going through hell, keep going.

Know or listen to those who know.

It's always too early to quit.

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

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

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