Miriam Webster’s dictionary defines integrity as, “the quality or state of being complete or undivided.” This can mean that someone with true integrity follows their own moral compass regardless of current trends. They cannot be persuaded into doing something that contradicts their internal values. A person who demonstrates true integrity is not easy to come by, so here are some traits they possess.
Trustworthy
They are that friend that gives you a direct answer and follows through no matter what. If you are having a birthday dinner and they say they will be there, they will be. Past experiences with this person proves they can be trusted.
Humble
They are not driven by praise and admiration, and do not brag about their accomplishments. The will do things for you simply because they want to see you succeed, not because they want a “good friend” credit.
Values the time of others
They are on time for social engagements and meetings. They understand that being punctual is a form of respect, and they are considerate of other people’s time.They will not have you waiting around for them.
Growth mindset
They are looking for ways to improve themselves. It could be through spiritual practices such as meditation or academic pursuits, like enrolling in a new course. They strive to be a better person everyday.
Welcome constructive criticism
They are aware of their strengths and weaknesses, and are open to being told when they have made a mistake. They use mistakes as learning opportunities to grow and improve, and take responsibility when they are at fault.
