I love the fifth principle of performance Zig Ziglar includes in his newsletter: “Happiness, joy, and gratitude are universal if we know what to look for.” Happiness is a choice. According to Abraham Lincoln, “Most folks are as happy as they make up their minds to be.” I find that I am happier when I focus on the blessings of life instead of what I don’t have or don’t like in my life. If we dwell on the negatives, we will live in negative circumstances. To quote Zig Ziglar, “If you are ungrateful, you will never be satisfied or content or joyful about your life. The greatest source of happiness is the ability to be grateful at all times.”
