Part of me is tempted to buy into the idea that the human animal just isn't naturally inclined to do more than a handful of hours of difficult or "productive" work in an average day. I honestly have no idea whether I'm normal or not, but I agree the pressure I put on myself probably isn't ultimately helpful most of the time. It's hard not to feel like others are getting way more done, and even harder to tell how much of what is presented is authentic.
