Have you ever watched a performance, music / dance / theater / gymnastics , as a non-expert in that area and just been impressed with what was appealing to you whether or not it was "hard"? Then you think about someone with lots of knowledge in that arena watching the same performance, and they are probably having a different experience. They may be thinking, "Wow! Look at that difficult move they just executed! Amazing!". You may have missed the impressiveness of it, but you knew what resonated with you. And the performer has a third version of the events thinking, "ooooh, I hope I pull off that triple-quadruple-back-slide doohicky perfectly!" and you may not even have known to be impressed with the challenge of the doohicky.
I'm thinking it's the same with our kids. We may be all impressed with our various ways of presenting/teaching a topic, but it may be hit or miss whether it works or not with the students. I'm thinking that they mostly only care about knowing that you care and that you have their backs and that if they are struggling with the learning, you will be there for them. They are not sitting back and thinking, "hmmmm, look at that student-centered stunt she just pulled off!" ... or, "wow, that's master teaching skills right there!".
So I'm thinking that, yes, we should strive to do our best with all our teaching skills, but maybe the most important thing that trumps the whizbang lessons is the fact that the kids see you caring about their learning and pausing enough and waiting for them to process and keeping your questioning and explaining processes churning to make sure they know you have a safety net for them in their learning journey.
I guess this is all to say that it's okay if I don't kill myself all the time worrying about presenting a lesson "just right" because as long as I honestly care during the lesson and am tuned in to what and how the students are learning, then I am doing fine.
