Best day at my old job: children paid attention and enjoyed my lesson plan. Joked around with co-workers, free food in the break room, get to go home early/on time.
Worst day at my old job: all but one class put at ratio, 20+ kids at naptime, late lunch, confrontation with a co worker, criticized for things I care about that no one else does, go home late because other people were sent home early.

Best day doing what I do now: babies sleep at the same time for two-three hours in the morning and afternoon, we go for a walk on a beautiful day, coffee, i take care of my home and my business while the babies sleep or play, i get cuddles and snuggles. I decide what we do and when and what activities to accomplish.

Worst day doing what I do now: babies only sleep for 30 minute increments or at opposite times, I don't sit down long enough to do anything, i get nothing done BUT I am still my own boss, at my own home, eating my own food, having my coffee whenever and wherever I want.

My "worst day" at home is still 10x better than any job I've had. It's only going to get better.
