Does the sheer amount of cool stuff out there feel overwhelming to anyone else? I want to learn this and this and this and that and this and that thing and this other thing over there.
Because of this I can't focus on anything because learning anything feels like it has infinite opportunity cost, spirals into anxiety. My irrational response is to watch Netflix because if I were instead learning X, I would be concerned that I'm not learning Y0, ..., YN for a very large N.
I'm probably halfway through my career and still feel like a perpetual beginner because of this syndrome. It has brought me many material and intellectual pleasures and tangible benefits, including a decent living; but I increasingly feel like if I want to progress in my career, it's time to specialize a great deal in a tiny subset of my interests. There's real power in being able to say No to things, and real wisdom in knowing what to say No to. I fear I lack both of these! It's vexing in the extreme.
