First big interior paint job as a newbie and it turned into a nightmare

I'm a couple months into painting full time and landed this interior repaint gig for a whole house, figured it'd be my big break. Been in the Carolinas so humidity's always a pain with drying times, but I went with Sherwin-Williams Emerald on the walls thinking it'd hold up. Customer kept changing colors mid-job, had to redo three rooms which ate up two extra days. Then the trim came out uneven because I rushed the caulking, and now she's pissed about bubbles from the moisture. Lost $800 on materials alone trying to fix it, and word's probably spreading. FML, any tips to avoid this crap next time?

Screw these picky homeowners who don't know what they want til it's too late, they ruin good gigs every time.
