This is not the thing I enjoy the absolute most, but it is the most unexpected choice for this question, and it’s something I enjoy very much.

I enjoy sleeping.
The act of abandon, lying on a soft bed and surrendering to a state of altered consciousness, is a freeing action. The day’s tensions shut off, leaving only the awareness of dreams, themselves a revelation. Dreams are like surreal television, giving me something to think about in the morning.
Being able to disconnect for eight hours, a scheduled mini-vacation every night, blesses me with the stamina to get through another day. I smile in the morning most days, feeling rested. There are days I wake up and want more sleep, but I wait till the next night to climb back into bed and start my beloved sleeping.
