What you write and put online are living documents. If you are wrong you can always change them. We are all wrong, it is just a question of being less wrong each day. The important thing is not about being wrong or not but about how you deal with it. Do you seek to improve and correct or do you double down? What more can we ask of a human than that they seek to be more right the next time? None of us can demand perfection unless we are hypocrites.
