I can, therefore I am.

If you're going through hell, keep going.

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

The dog that trots about finds a bone.

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

Never complain and never explain.

You never know what motivates you.

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

If you think you can do it, you can.
