When your mind is unplugged—from devices, work, drama—the battery recharges.
Plug it in to one of those things, however, and the battery will drain.
If you find your mind in a nonfunctional state, maybe it’s not because you’ve been plugged in too long—but, because you haven’t been unplugged enough.
