If you think you can do it, you can.

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

Wherever you are - be all there.

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

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

It's always too early to quit.

Expect problems and eat them for breakfast.

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

Know or listen to those who know.
