You're an old-timey mainframe guy if I remember right, aren't you? In my experience people from that world start from the hardware, then pick the software, then decide what to do with it. There's the old joke that you can write COBOL in any language, and I've seen it. (In TSQL, for what it's worth.)
Instead, figure out what kind of work you want to do, what industry, and see what they're using. Then learn that.
