Wednesday is halfway through. That is a feel. Hell,all the best cars are built on Wednesday because that's when you are in your groove! Thursday? Well tomorrow is Friday, so you are all pumped and excited.
Tuesday is just fucked. No Holidays take place on Tuesday specifically (Labor Day and Memorial Day are on Monday, Thanksgiving is a Thursday. Truth is that nothing important intentionally happens on Tuesday.
Tuesdays are the worst. I can usually scrounge up enough motivation over the weekend to power through Monday, but it's gone by Tuesday and it's not even halfway through the week.
