Better than a 7am appointment, now that will really ruin my day. Doesn't matter if I got 8 hours sleep the night before (I definitely didn't but let's pretend for a moment), I'm going to be tired for the rest of the week.
Sadly most people can't make enough money to survive doing that, because any job that let's you work from home WILL requires appointments and meetings even if they're just over zoom. And zoom appointments are about 500 hundred times worse for me shudder.
I have the opposite experience. I use early appointments as a tool to get me up and moving, dressed, presentable, etc. Then I have some momentum for the later part of the morning and afternoon.
