It's inevitable, as we move through life there will be blunders, we will make mistakes - many of them. When we make mistakes often we are angry at ourselves and feel badly. There is a positive side to making a mistake. When we make mistakes we are able to learn from them and utilize them so we don't repeat the same mistake again. Mistakes are stepping stones to use to get to where we want to be, to reach goals and become the person we strive to be. So, when you make a mistake don't focus on the mistake and feel badly for too long. Acknowledge it and take note of what could have been done differently and going forward use what you've learned!
