To quote Damon Runyon, "One of these days in your travels, a guy is going to come to you and show you a nice, brand new deck of cards on which the seal has not yet been broken. This man is going to offer to bet you that he can make the jack of spades jump out of the deck and squirt cider in your ear. Now son, do not bet this man, for as sure as you stand there, you are going to wind up with an earful of cider."
In short there's always going to be someone doing something you are doing more polished than you're doing it, doing something you aren't doing and doing it more polished than you presume you'd do it, and/or doing something you aren't doing and have no hope in heck of ever figuring out - and doing it more polished than you presume you'd do it. Always.
The flip side of that is not to sell yourself short either. Yes, all of us always can improve. We can always do better. We can always learn more (and learning more is that varyingly sweet and sour cocktail a serious student of magic frequently drinks - and sometimes has thrown in their face.) But all of us had to learn. The master you're admiring was once right where you are now. And here's another little secret: that person you're admiring may have invested the better part of a lifetime into everything they just showed you. In some cases "everything" means a huge repertoire; in other cases "everything" may be only the three things they just showed you. The fellow with the cider-squirting jack of spades? That may be the ONLY trick he knows and performs (granted, he may very well not NEED to know or perform anything else if he does that one.) A young magician visited Harry Blackstone Jr. backstage after his show and said "It's great to meet you, Mr. Blackstone! I'm a magician too and I know over 200 hundred tricks!" Harry replied "Wow! I only know those 12 you just saw me do." This echoes the other saying that an amateur magician does many different tricks for the same audiences while a professional does the same tricks for many different audiences. But it's the quality I'm focusing on here, not the number of "bookings" per se (although that obviously is a factor in terms of experience too.) In a different analogy, suppose you and I meet in the parking lot as we're arriving at a golf course. We strike up a conversation, learn that we're both here on vacation, discover that we're both amateurs and we're both looking for a person to share a round with and that we've both been playing golf for 20 years. So we go out on the course and you absolutely wipe the greens with me. Why? We really are both amateurs and we really have both been playing for 20 years. But the thing I missed was that you're from Florida and I'm from Minnesota. So while you've been playing for 20 years, you've been playing for 12 months/year x 20 years whereas I've only been playing for 6 months/year x 20 years. Same number of years, but you actually have TWICE my experience.
So all we can all do is to enjoy that journey. While there are many similarities en route, it's ultimately unique for all of us.
