Best points that i noted there is....

Rule 1 Stand up straight with your shoulders back

This is in general OK, posture is important. But on the other hand you have to be careful not to appear to stiff or people will think you a snob. 75%

Rule 2 Treat yourself like you would someone you are responsible for helping
This is silly. A person you are responsible for helping may have different needs and wants then you. 25% at best.

Will follow it for better improvement
