"Never show anyone. They'll beg you and they'll flatter you for the secret, but as soon as you give it up... you'll be nothing to them..." Quote from the prestige about magic.

Agree - I consider myself a social hacker... and I'm constantly tempted to show off my methods... but I try not to. A trick is more impressive if someone doesn't know they are being tricked.

And if everyone does it... it looses its magic.
