Today I:

Tidied up the breakfast alcove and mopped the floor
Did some indoor exercises
Searched my computer for an income tax voucher I didn't realize I'd need, and couldn't find it
Played piano
Cleaned up bedroom
Took 1-mile walk
Talked to some neighbors outside (an accomplishment since I tend to not be very social)
Ran the dishwasher
Did animal care
...getting enough sleep helps with energy.
