Pale Blue Tint! You answered your own question! (it's amazing how that's always the way...)
You're right. We are ALL looking for our purpose. Something extra that gives meaning to your life....that brings inner peace... yes! Some people don't even realize what you can feel in your bones. That you voiced that means that you are well on your way to finding what that 'something' is. Trust that you're on your Path and keep following your intuition...you will be guided to what your purpose is!
