Good thoughts Asher, and everyone, but I really like how you put everyone into two groups.
I would say that you're either moving forward or standing still...and if you're standing still you'll be sliding backwards before you know it.
I like what David Stone said about the difference between and professional and an amateur. I'll look it up to quote it here but to paraphrase until I get home:
...the professional is someone who shows up on time (hopefully even a little early), who takes care in dress and appearance, and who does his or her job well. Any amateur with a little sense is capable of that much, right?
He also made the statement (right before):
People often talk about the difference between amateur and professional magicians --and it drives me nuts. If there's a distinction to be drawn, that certainly isn't it. Before becoming a professional, you have to be an amateur! Many of my friends are excellent amateur magicians, and I know some frankly dreadful professionals.
I'll let you buy the book for the rest of his thoughts on the matter.
With that said, my previous statement was for the posts at hand. Since there are no tests that specifically separate novice from amateur from beginner from intermediate handlers from experts, I think it's probably better to let everyone else to come to the conclusions. Don't worry about being a professional, or an expert, just work hard and eventually it will be recognized.
You shouldn't take everything that everybody says as fact either...tricky subject and I'll end with this,
Last time I checked this was America (at least where I am).
