Acting is just faking it good.  Can you act like a doctor if you are told what to say.  Some can.  Some can convince you that they are a doctor.  In the old days they would have found that they were good politicians or salesmen.  Acting is a good talent to have but it needs to be rooted in some reality.  If you can draw upon past experience it will make your acting more authentic.  The better the actor the more successful he will be.  Some of the best actors have little or no formal training.  They were born with the talent.  They can sing dance and act like a dream.  acting, according to Wewege, is the most difficult kind of faking.
