Need Training? Or You're Just A Natural

IN MY OPINION;

WILLIAM REYNOLDS;

DO ACTORS REALLY NEED TRAINING? OR, ARE THEY JUST NATURALS?

Like any skilled profession you need to practice in order to become objectively good.  With regards to acting this can be accomplished in a couple of different ways: 
- you can do a lot of plays in school and learn as you perform and continue that in community theater and work towards becoming a professional stage performer 
- you can audition a ton and learn what works and what doesn't by doing that.  I don't know if Aaron Paul was telling the truth but he claimed to have never taken an acting class and he learned from self analysis through auditions
- you can take classes and hire a coach  Regardless of what you do you need to practice and perform in order to become a good actor....But is that what you should be satisfied with?  Do we want to be "good enough" or the best we can be?
I can't think of a single competitive endeavor where a coach or mentor of some kind isn't necessary.  No athlete will ever qualify for the Olympics without multiple coaches in their life to get them to achieve their peak physical performance.  Nobody will ever get a PhD without an advisor to guide them through research.  
So long story short I think it is possible to become a professional actor, in the sense that someone will pay you to be in front of a camera, just on your own if you have the right combination of natural charisma, connections and luck.  But if an individual wants to achieve at the pinnacle of their acting potential they need some kind of FORMAL TRAINING.
