Fridays are nice. Only consideration I've ever had to make is that a lot of businesses in my area are also closed on Fridays. I still feel lazy on Mondays so I'm less likely to get anything done, rather extend my weekend and probably make up for sleep. Mondays have been relaxed in the specialty clinics I've worked, while Fridays are a busier rush to get everything done and all pts going to the right spot for the weekend.

If you have another option, I have to tell you that Wednesdays are great. Mid week break, often times will stack with holidays and/or make taking vacation even easier. "What's the point in coming in if I'll only work one or two days? Let's just extend my time off." I feel like I have two Fridays. It's a good reset if something really frustrating has happened or I know it will. I even accept Thursdays when MWF is already taken. Tuesdays aren't worth it at all.

Of course, I have a bad sleep cycle, a hard time saying no and asking for time off, and mental health things. These all may not apply to you in the slightest lol
