Someone has an expectation of you that you will not meet. It could be a supervisor. It may be a friend or a relative. There are a host of expectations piling up or slowly collecting with your name on it. You will not meet many of them. In other words, you will fail somebody today.
Make the simple acknowledgement to yourself that this is true. It’s already in the future of this day. Accept that and turn toward what else the day has for you. You will fail somebody. What else is there?
