Integrity: to be true to your feelings, values, and commitments.
Loyalty and honesty are principles because you used it in everyday activities. Like you used loyalty with your parents. Also you used honesty with your parents it is a the best way to go.
I live by honesty, respect, and responsible. I live by honesty because I think people should be honesty because when you get you out in the real world nobody will give a crap about you and your statements. I live by respect because I think you should respect all the people you meet all the time. I live by responsible because I want to responsible for my own things, assignments, and duties.
