"In my 30s I used to go to the gym even though I hated it. The purpose of going to the gym was to postpone the day when I would stop going. That's what writing is to me: a way of postponing the day when I won't do it any more, the day when I will sink into a depression so profound it will be indistinguishable from perfect bliss." - Geoff Dyer
So I joined a gym, and have been going quite often. A half hour on a treadmill followed by 15 minutes on an elliptical, or spinning class once a week.
I like the way the gym makes me feel, and not just physically. Mentally, too. I sleep better, and I wake up more energized between the ears. I am regaining a creative energy that is normally absent once it's too cold to be on a bike. I like it.
But it has made me realize that I'm not writing enough right now.
