So the sign of a wise person is their ability to change once they realize they made a mistake. Whether you are a former liberal who's finally come around, or perhaps an organization admitting that you've hired some real idiots. OK, I had to get that out of my system. Now, remember, making a mistake doesn't define you. It's what you do after the mistake.
You can either say, I admit what I did, and I'm ready to try something new or just keep blaming it on climate change. It's especially true when it comes to Donald Trump.
