The secret of getting ahead is getting started.

I can, therefore I am.

The dog that trots about finds a bone.

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

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

Things do not happen. Things are made to happen.

It's always too early to quit.

Know or listen to those who know.

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