What is it?

No matter how busy I keep myself, lately I feel like there's something missing. I can't shake the feeling, but I don't quite know how to fix it either.
Have you ever felt lost? Not unhappy, just unsure what path you're supposed to take next. Right now I'm at a fork in the road, just staring straight ahead.

And I wish I could jump on a plane, look down and see which path has the happier ending...
