Monday has become such a meme that it actually can be a decent workday. I know some workplaces bring in snacks on Mondays specifically because of the “It’s a Monday” thing. Plus, if I had a good weekend, I still feel a little bit recharged from it going into the work week.
Wednesday is hump day, which for me is encouraging to know that once lunch is over, I am halfway through the week.
Thursdays are sucky, but not too bad because you have Friday to look forward to, and Fridays obviously are right next to the weekend.
Tuesdays are still in the first half of the week, but they don’t have any of the culture of memes around them to make them fun, even in a “we’re all in this together” kind of way. So for me, they are the worst.
