I have some (imperfect) sense of how sharp I am at some time, or am likely going to be in the near future, which influences when I tackle tasks. Algorithm that must be correct? It's not going to be working through that first thing in the morning, nor squeeze it into the 30-minute gap between 2 meetings. And hopefully it doesn't have to be done on that day I didn't sleep well, because I can tell I'm not at my best. When something that needs hard thinking must be done right then, I can do it (and probably still better than most people, if it's something I'm good at). But I often have the feeling that I'd be thinking of more possibilities, or not making "careless" oversights, were I not fatigued or distracted. Occasionally, I've pulled off some of my most meticulous work despite being fatigued. But it felt like more exertion than it should, and presumably I wasn't spotting all the opportunities that I would've under better conditions. That said, as someone who doesn't blog, I don't much filter my more casual, off-the-cuff Internet posts by sleep/sharpness. Actually, Internet posts are more likely to be a morning warm-up, or a break between tasks. Maybe, if Internet posts paid better, I'd start optimizing sharpness for them.
