Michael is the kind of guy you love to hate. He is always in a good mood and always has something positive to say. When someone would ask him how he was doing, he would reply, “If I were any better, I’d be twins!” He was a natural motivator.

One day I went up to Michael and asked him, “I don’t get it. You can’t be positive all the time. How do you do it?”

Michael replied, “Each morning I wake up and say to myself ‘Mike, you have two choices today. You can choose to be in a good mood or a bad mood.’ I choose the first. Each time something bad happens, I can choose to be a victim or choose to learn from it. I choose to learn from it. Every time someone comes to me complaining, I can choose to accept their complaining or I can point out the positive side of life. I choose the positive side of life.” Michael continued, “Life is all about choices. The bottom line is: It’s your choice how you live life.”

Several years later, Michael was involved in a serious accident, falling off 60 feet from a communications tower. I saw him about six months after the accident. I asked him what had gone through his mind as the accident took place.

He said, “I first thought of my soon-to-born daughter and then remembered I had two choices: I could choose to live or I could choose to die. I chose to live. I knew I needed to take action. So when a nurse kept shouting questions at me asking if I was allergic to anything, I took a deep breath and yelled, ‘Gravity’. Over their laughter, I told them, ‘I’m choosing to live. Operate on me as if I am alive, not dead’.”

Michael lived, thanks to the skill of his doctors, but also because of his amazing attitude.
