Ultimate Success Formula?

Man alone, of all God's creatures, can change himself for the better.

Anthony Robbins in his Personal Power II tape, says that the following are The Ultimate Success Formula:

1. Know your outcome.
2. Get yourself to take action by deciding to do so.
3. Notice what you're getting from your actions.
4. If what you're doing is not working, change your approach.

What is your view about this success formula?

Anyway, I find it very similar to Six Sigma phases of Define, Measure, Analyze, Improve and Control (DMAIC).
