Waiting or Doing?

Wow I guess it has been way too long since my first installment. Well here it is. Any one else out there ever felt like this: What do you do when you know you are supposed to be doing something, but you are not? What do you do when you are not fulfilling your purpose? Do you run off into the blue and just "pick" something to do?, or Do you wait until the path is clear? Seems like an easy answer, but truthfully, how many times have you; just like me tried to make it happen? So what is the deal?
