You can continue to give yourself a hard time about a decision. But beating yourself up over flawed vision is not going to help with the problem! Approaching it with a renewed level of vision and a willingness to see things differently will! You now have an opportunity to turn a mistake into a new answer! But this will not work if all you can do is focus on a problem and how poorly you felt you performed in dealing with it. Focus on solutions and not as heavily on problems!
