Experienced vs.Newbie: Infancy?

Next, regarding a recent discussion of "experienced" vs. "newbie", I don't
come down definitively on either side.

My own two cents, for whatever two cents coming from me is worth is, all due respect to a guy who actually knows me and has graciously mentioned me as an experienced screenwriter, that, to tell the truth, I don't feel that experienced.

Yes, in the past three years, I have been hired to write or doctor nearly 20 screenplays, sold an original, saw one feature written-for-hire get produced, am expecting 2-3 others to be shot within the next year and I have been teaching college screenwriting classes for the past five years.

My point is that I feel like an infant, okay, maybe a toddler, and that I still feel like I have so,so,so much to learn about the art and science of screenwriting, I feel like I have just begun to crack the surface of what it means to be able to write a screenplay. I have seen movies where I just have to throw my hands in the air and say "You know, I could not have written this screenplay. I am not smart enough, deep enough or creative enough to have written this screenplay."

So, I keep going, learning, everytime I sit down to write, hoping to one day get it "right."
