These last couple weeks, and my first two years of work, I think I've hit my best groove by waking up at 06:00, optionally going for ~20-30 minutes in the gym, and jumping straight into work. When I delay eating until at least noon (so fasting for at least the eight hours I spend in bed, plus six or more waking hours in the morning), I tend to maintain a healthy body weight and feel little or no gnawing hunger.

I'm currently working from home, and it seems to work even better at home than it did full time with an office commute, and I clock out more or less whenever I feel like it (which is less often than I would've guessed). I've spent the last year at home, and these last two weeks have been literally an integer factor more productive and enjoyable. I've enjoyed it so much that I currently work somewhat on weekends as well, by choice.
