It’s interesting we came to different conclusions on this one — I think there’s something here worth comparing notes on, but I’m not quite sure what it is. In my experience, working a consistent 7 hours every day will quite rapidly burn me out.

I think it’s the definition we’re using for “work.” When I work, I work hard, and I dedicate my entire mental focus on the task. Doing that for seven hours straight sometimes feels like a small marathon in itself. Perhaps you’re just more effective.
