If I could teach only one value to live by, it would be this: Success will come and go, but integrity is forever. Integrity means doing the right thing at all times and in all circumstances, whether or not anyone is watching. It takes having the courage to do the right thing, no matter what the consequences will be. Building a reputation of integrity takes years, but it takes only a second to lose, so never allow yourself to ever do anything that would damage your integrity.
A word of advice to those who are striving for a reputation of integrity: Avoid those who are not trustworthy. Do not do business with them. Do not associate with them. Do not make excuses for them. Do not allow yourself to get enticed into believing that “while they may be dishonest with others, they would never be dishonest with me.” If someone is dishonest in any aspect of his life you can be guaranteed that he will be dishonest in many aspects of his life. You cannot dismiss even those little acts of dishonesty, such as the person who takes two newspapers from the stand when they paid for only one. After all, if a person cannot be trusted in the simplest matters of honesty then how can they possibly be trusted to uphold lengthy and complex business contracts?
There is a plaque on the wall of my office which reads: “Do what is right, let the consequence follow.” It serves as a daily reminder that success will indeed come and go, but integrity is forever.
