The dictionary defines integrity as follows. Take from wikipedia
Integrity is a concept of consistency of actions, values, methods, measures, principles, expectations, and outcomes. In ethics, integrity is regarded by many people as the honesty and truthfulness or accuracy of one’s actions. Integrity can stand in opposition to hypocrisy, in that judging with the standards of integrity involves regarding internal consistency as a virtue, and suggests that parties holding within themselves apparently conflicting values should account for the discrepancy or alter their beliefs.
This is the first of our 6 tenets and one of the most difficult to master. A year or so ago I had someone comment to me that I lacked “integrity,” I asked for a “specific” but got no answer. The truth is everyone on this planet in some part of their life lacks integrity. This is why I say it is so difficult to master. When it comes to integrity you need to day to day evaluate your progress and keep on trying. Like all things in life this is a work in progress. You will fail in some aspects and excel in others. But the main thing is to keep on working day by day to become a better person. To my way of thinking this effort for constant and never ending improvement is the path to having integrity and living a happy life!
