I do this too. But i think for me, its that I get to a point where I have a really good understanding of something, but realize that spending incremental time on even more expertise on the subject has only marginal returns. Like if I already have a good understanding of a subject or technology, it doesn't really make much sense for me to keep learning the nitty gritty details which I may never use. But instead am satisfied that I have a good enough base of knowledge that I would know what to look for if I encountered something I wanted to know within the field.
