Thankfully, mistakes happen. Without those mistakes, we'd never make forward progress into the new. What's often frustratingly confusing about those mistakes is when we make them along a proven and trusted path. Even then, if we make enough of them, we wind up changing that path for the better. The older I get the more I am thankful for my mistakes: learning opportunities I would never have if I wasn't comfortable making mistakes. I believe it was Albert Einstein who said "The only sure way to avoid making mistakes is to have no new ideas". After you get over your Doh! I made a mistake moment, replace it with a smile. If we can get our mindset right, mistakes are a gift.
