Here's a little trick for starting a day off.
First, think of the way you'd spend the day if you had no obligations at all, if you could do whatever you want.
Second, identify those things that must happen today or else tomorrow or the next day will suck.
Third, note the commitments you made to other people and/or social possibilities you'd already been considering which still sound appealing.
Now, build a day which has all three represented, with adequate time between to not feel rushed. I recommend cutting from group three to ensure you get enough of group one.
