I agree with a lot of what Indigo wrote. Interactions among others, playing the political game helps getting career goals. I have been told that I have the political sense of a cow and even being right, didn't matter. So a choice where you control the work, which doesn't happen immediately. Look at what kinds of things you like. But also try and build your social network. Join some clubs, play tennis, try and be out there. It all helps.
Good luck.
