This isn't necessarily bad, just that the thing you learned wasn't actually something you needed to learn. I don't mean that negatively though. For example, I use JavaScript and Python at work. I recently read a Haskell book and learned enough to do its exercises. I won't use Haskell at work any time soon and I don't have that much time for personal projects... so was it a waste of time? I don't think so, since I enjoyed the process of learning and a lot of concepts will stay with me. If you want to do project X and can't focus on learning what you need for that, that's a problem. Otherwise, you're not much different from figures such as Theodore Roosevelt who'd read books on a thousand different subjects every year, for fun.
