Ask HN: How can I come out from analysis paralysis?

Quick and probably useless suggestion: Build a product. It's hard to learn a language/framework/technology "just because" -- it's much easier when you're working on a specific project. (You mentioned Go and Android; combine those two; with Go 1.5 just now being released with solid Android support, that's a green field, i.e., there's very little that's been done in that area and people would be keenly interested in anything you might do.) Pick something and get started, and resign yourself to the fact it means over the next year you're going to be acquiring expertise in that and not any of those other enticing technologies. You can't learn everything. Sad but true.
