There are four kinds of people in your life: those who add, subtract, divide and multiply. The people who add to your life and the people who multiply your joy are easy to identify. These people make you better.
Be very cautious of the people who diminish you and cause you harm. Run away from them. Your friendships with abusive and angry people will put you in peril, and you will become less than who you should be. These individuals divide your effectiveness, subtract from your happiness, and lessen your feelings of self-worth. Be careful where you choose to spend your time. Those who do not increase you, inevitably will decrease you.
