Indi, I'd guess you are of maturing years, perhaps a significant number of hours under your belt?
I'm possibly in that area too!
The lesson I'm trying to teach myself is that because I am getting "very experienced" in what I do, now; doesn't necessarily mean that there is not a better or more effective way of doing it.
I try my damndest to remain 'available to change', open to ideas, though sometimes one has to bite one's tongue.........
The old ways are not necessarily the best, methinks?
