From the quality of your cup of coffee, you already know you shouldn't expect a lot out of today. But don't get upset if things progress even less than you think they will. One day's failure does not mean that you will continue to under-perform. The worst thing you can do is to lose heart and stop working towards this goal. You are where you need to be, so just clear your mind and try to accept the fact that you cannot control this timetable: just yet. Let other people take the wheel for a while.
