Just a reminder: It's winter. The days are short, the nights long. Two major holidays fall in winter, followed by a month of cold, miserable weather. Only people in the Southern Hemisphere and equatorial countries aren't slowly thawing and coming out of hibernation. Don't be too hard on yourself because you failed to get on the bike, the trainer, the Spinning class, etc. Be happy that the days are lengthening and Spring is but 3 weeks away.
Today we hit 70*, and more of the same is predicted for tomorrow. I'll be getting in a ride about noon, and no matter the length, intensity or elevation, I'm going to have fun. I'm in good company, I see.
Glad to hear you're getting the mojo back, DG.
