Live by the Golden Rule.
Be honest with yourself and make decisions as objectively as possible. If you're uncertain, seek the opinion of a trusted mentor.
Surround yourself with people who glow with integrity.
Speak up when you see a breach of integrity. Silence can be as hurtful as words or actions. Cultivate dialogues for stating your honest opinion in uncomfortable situations.
Promote integrity by acknowledging the wise choices your friends and coworkers make.
Keep your promises, to yourself and others, and follow through on commitments, even when delivering on the promise is difficult or when a more exciting opportunity presents itself.
