I always drive myself INSANE trying to put a schedule together.
I've been convinced Wednesdays are terrible, and my last few Wednesdays have been great!
Alternatively Sat/Sun is usually good but my last few have been iffy.
It's kind of funny the way our brains rationalize this stuff.
The only major times I've seen traffic dips is like Major sports events or like "go out and get drunk" holidays.
I like to switch up my schedule sometimes, I try to keep my hours the same, but I'll switch up my days off every once in a while, just to see what's up.
It becomes a balance of appreciating the great days, as well accepting the bad days as something that's out of your control.
I do usually find the beginning of the month is better for me than the end though.
If you're really feeling the pressure of it, taking a step back and a little break is way better than having super stressed out cam shows lol
