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 doesn’t mean that you’ll continue to underperform. The worst thing you can do is to lose heart and stop working toward this goal. You are where you need to be, so just clear your mind and try to accept the fact that you can’t control this timetable yet. Let other people take the wheel for a while.
