How to be successful?

I wonder if being successful in everything you do is really that difficult. Seems to me that if you:

1. Do what you say.
2. Show up on time.
3. Say please.
4. Say thank you. And be thankful.
5. Say and be sorry when you screw up.
6. Learn from your mistakes and don't give up.
7. And never let your success go to your head.

Success won't be far off.
