I myself am now and expert at insulation and all the vapor-permeable and vapor-blocking membranes/foils/foams that come with it.

It came at great cost though, I hated the process of learning and the execution. I was less than happy for some years. But I feel even more uncomfortable vibe-home-improving than I do vibe-coding. The place is starting to look nice now though.

It's a personality trait that has its pros and cons I guess.
