For some people, Friday drags. Work is what stands between you and the weekend.
For me, Friday flies. I usually don’t have a meeting for work on Friday, so I can use it to try to catch up with all the things I haven’t gotten done the rest of the week. Thus, for me, Friday is always busy, and I could use more hours in it.
(Friday can also be a very satisfying day, since I’m checking off all those items on the to-do list.)
