There’s a voice in my head that encourages me to get out for my run, or ride or, in this snowy season, a cross-country ski. You’ll have fun, she says. And even if it’s not fun today, she assures me that I’ll feel better for having done it. She’s pretty much always right. There’s another voice in my head, which tells me that I’m out of shape and slow and why bother. Sigh. I hear her, all too well, even though she’s mostly wrong.
