I too have used the “buckets” analogy. Please allow me to continue and overuse this metaphor.
I rarely try to learn anything just for the sake of it. I learn what I need to learn as whatever I’m working on demands it. But I try to know enough so that when I read tech news, I can place what I’m reading into mental buckets. Then I can, metaphorically, reach into those buckets when those topics come up. Plus, I can keep an eye on how full those buckets are. If I find myself putting a lot of stuff into one bucket, I might plunge in there and see what’s going on as there is clearly something in the water.
