I don't agree with that at all. . . there are "hobbyest" and "amateurs" that know more about magic, especially the technical face of magic, than most any of the pros out there. Gary Darwin is one person that comes to mind; he loves magic, has penned a few awesome books about magic, but he rarely, if ever, performs an actual act/show. Yet, you can't beat him when it comes to his literal skills and knowledge.
Chuck Jones pointed something out to me years ago; working pros are too busy working to be up to date in innovations, new effects or even who's who. They know THEIR SHOW and that's about it.
Yes, someone with genuine experience in given niche areas will be able to shine light on that specialty; that's like someone asking me about doing close-up, I've rarely worked as a close-up guy and I'm not technically adept in that field so I can't offer too much in way of guidance that's practical or realistically applicable. However, ask me about the two or three fields I've invested years of time working in; well, I'm pretty much a big juicy apple in said barrels, one that's difficult to challenge. . . I know that sounds very egotistical, but when you have people of note claiming to be "your fan" you must be doing something right. . .
My step-kids loathed the fact that I was usually right more than I was ever wrong and even when I was "wrong" about things, it was by degree, not a direct black & white contrast. I've seen this same scenario play out in the lives of my various mentors (and even shared the "resentment" some of my students have with me when it came to their always being "right". . . it's frustrating! But it is likewise reassuring, knowing that you have someone that certain anatomical orifices from a hole in the ground.
As I said, "when the student is ready, the teacher will reveal themselves" and trust me when I say, the best teachers will be the one's that call you on the rug, who constantly correct you, and make you want to bite nails you get so livid with them. They are challenging, frequently crass and would appear to not give a damn at times. My own key Mentor not allowing me to refer to him as such until we'd worked a few dozen shows and several years together. When I started flooring him using props from our shared inventory that was when he started having pride in my abilities and as such, security in passing the mantel (as it were) to a new young face.
I'm not alone in this sort of thing but the catch is that we get the teachers we need not the one's we like or wish to have. A true Mentor rarely comes in that perfected form we envision; they are just as screwed up as everyone else in your world, frequently worse. They have baggage, tempers, vices, and more and so, we become as important to them and their ability to function in the world as they are to us and our personal growth.
Just let things move by naturally; you will have people notice you over time. Don't be afraid to ask those whose work you admire to show you things or to invite them out for coffee; strike up a friendship! You will learn but such people may never become the sort of guide you're dreaming about.
Best of luck!
