What's the definition of integrity and what does it mean to me? Integrity to me means doing the right thing even when nobody's looking. I think that's what matters most. Or doing the right thing even when you know you won't get credit for it. I think is almost more important. It's acting as if everyone was watching even when nobody is. Being that person that is never even questioned if someone else can depend on you. They just know from the get-go based on your behaviors, your personality, how you approach anything in life can reflect on you being someone that can be trusted to do the right thing to get the job done when it matters.
