”Real integrity is doing the right thing, knowing that nobody's going to know whether you did it or not.”

~Oprah Winfrey

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 we never allow yourselves to ever do anything that would damage our integrity.
