Today is about today.
Every teammate is going to make a mistake from time to time. The key to giving second chances is about making today about today. When I keep score on the mistakes of my teammates, I will struggle to keep a single mistake in the correct context. Just because someone made a mistake in the past, doesn’t mean that they are guaranteed to repeat that mistake for the same exact reason. It’s important to keep the past in mind but if the past causes me to put a label on someone, I must be careful not to fill in the blanks of the current situation with the historical record I am keeping. My bias may be true, but it’s not automatically true.
