ObLaDiObLaDa: Have to agree with you totally! I don't know that I would be brave enough to take that art class but learning to have thicker skin would be great! OK...so I am an ENFP but my E & I are very close and I certainly swing between both types often enough to confuse myself! But that said I am an ENFP but perhaps a slightly more introverted one (if that makes any sense).
I have posted on here some time ago...and the only thing I can add is follow your dreams. It doesn't matter how obscure or distant they may appear...just believe and embrace them. Also be very careful not to spend too much time around negativity because chances are you may also be an empath which means you absorb other people's energy and often experience it as your own. Read up on empaths as you'll recognize yourself if you are one.
