One does not look to others to justify his actions. One makes one decisions according to the firm, but not rigid, principles by which one lives.
It takes dedication and hard work. It takes self-discipline and perseverance. There will be many times when it would be easier for you to relax your standards and let some of your principles slide, times when no one would know but yourself.
Thomas Jefferson explained how he dealt with such situations stating, “Whenever you are to do a thing, though it can never be known but to yourself, ask yourself how you would act were the entire world looking at you, and act accordingly.”
