You have too much to do and too much to think about.
Workdays get longer.
Weekends get shorter. All you want to do is carve out quiet, mindless times for your energies to juice themselves again.

You can unknot neck muscles sore from too much time hunched over the computer or lower back muscles strained from too much driving. Time in a home spa can be as beneficial as taking your multi-vitamin.
