Just wondering how many of those saying, "never sell a trick" came up with all of their own, since obviously if you cannot sell a trick, you cannot buy one either. If they bought them isn't that saying something like "never sell a trick unless it is me that wants it?
It sounds a tad hypocritical to me but that is just my take on it
Welcome to Penguin.
It's not our place a magicians to sell the effects to make a quick buck. Especially to some idiot who would pay just to know the secret so that they could act smarter by telling everyone how it's done. What other reason would a lay person have for dishing out money to be shown how it's done. Maybe they want to learn that one trick, but why. It's not worth it to give up a secret so that a person can perform or try and perform that one trick. What ends up happening is they expose the effect and give away the secret. If they are truly interested in magic, they will start from the beginning and work their way up. If someone is willing to pay ME money to learn one trick, then they should be willing to spend the same or less to learn a bunch of tricks. If they are only interested in the one trick and nothing else, then if you sell the secret, you might as well give it away. I have never paid someone to show me how to do a particular effect. I have asked where I can learn something and then researched on my own...but never offered to pay someone to show me. In addition, I have never entertained anyone's offer of money to show them how I did something...and I have been offered quite a bit of money for one simple effect. It's just not worth it. I would begin to lose respect with myself.
Purchashing merchandise and publish materials is totally different than accepting money from someone to tell them how to do a trick that you just did. It's not hypocritical at all.
