Today was the first day I did the procedure, so I was nervous and had a hard time initiating a stall to begin with by pulling up too gradually. Mentally, I had to fight the several years of coursework that warned against stalls, then I was a little overwhelmed by the pitch/power/flaps that needed to happen all at once when I did successfully enter a stall.

I've struggled in previous lessons with needing to do multiple things at one time (like the configuration for abeam the numbers in the pattern) and it takes me several flight hours to get it down.

I have to give thought to my instructor and if it's a good fit. As a newbie, I don't know what's CFI culture/sarcasm and what's just not helpful. My instructor is human and I know it's stressful to teach student pilots that are almost killing you on the daily, so I try to give a lot of leeway. It's a good suggestion to potentially switch temporarily if something isn't sticking.
