I am also most productive before 10AM, but that is usually because 6-10 is the only time I have to work, because at 10AM, meetings usually start, and they don't stop until around 3pm (sometimes as late as 6pm near releases), and by then my entire soul has been sucked from my body and I need 12-16 hours to slowly reel it back in. I love WFH, but this is the one part that has seriously killed me. Before WFH, management was rarely in the office before 10AM or between 12PM-2PM and I would sneak out at 4PM every day. Now that everyone is WFH, the concept of work hours has died. I still have a hard stop at 4pm, but doesn't stop me from getting calls or texts even as late as midnight - I just refused to answer anything after I'm done working and put my phone on silence.
