LOVE ALL, TRUST A FEW, DO WRONG TO NONE! - William Shakespeare
Having integrity is actually possessing a way of life that is strong in different moral principles. Characteristics such as honesty, sincererity and straightforwardness need to be in your daily living patterns. Having these characteristics is most important in the business world if you want to have any long-term success.
As you grow up and experience different friendships, you will realize that there few people in whom you can completely trust in. It is important for you to have some kind of knowledge for those times when you need to put your trust in another person. One of the most important rules that you should follow is to never give a person a reason to say that you did not tell the truth. I remember talking to my mentor about integrity and he told me this: "Trust is like a thin bread. Once you break it, it is almost impossible to put it together again."
