I can, therefore I am.

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

If you're going through hell, keep going.

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.
