I heard a quote the other day that made perfect sense to me. One of the NFL Hall of Fame inductees mentioned it as part of his speech and it really resonated with me (and Chief too.) "When you think things are going good, they're really not that good. And when you think things are going bad, they're really not that bad."
We need to learn to live with a certain amount of dysfunction in our lives. It's healthy because it's reality. When we see things for what they really are, we have a much better grasp on the truth around us. An honest, real view of a situation is the greatest advantage for solving a problem or resolving an issue.
This is a tough lesson for an OCD, Type A personality like me. But, over the years, I've learned to just roll with the punches. I'm getting better at it all the time. Life is too short to get all flustered when things, people or situations are not perfect. (Or at least not what you interpret as perfect.)
Learning to think with this open-mindedness also allows freedom for your own dysfunction. And it's going to happen sooner or later. You'll be a little more tolerant of your own mistakes if you learn to accept and move on from others that are out of your control. This will make you happy, I assure you.
