“Work on tricks only for yourself” versus “Work on tricks to please a crowd” is a false dilemma. Work on tricks for an audience of like-minded space chimps that share your weirdness.
The prime directive is this: get better. Shun that which doesn’t make you a better performer and lurch toward that which does, however clumsily. Watch other performers, a lotta films, listen to music, and read everything. Novels, memoirs, essays, psychology, hard science, graffiti, magic books. Read the labels on soup cans.
Take walks. I hate how this advice sounds like something a preposterous old geezer would say while smoking a pipe, but, sorry, it’s true.
When you have a good idea for a new presentation or method, write it down immediately. No exceptions. Experiment, develop material, practice, rehearse. Do this for 2 hours a day. If you don’t have 2 hours, try 3.
When you put together a new routine, think of it as testing an idea. When it doesn’t quite work for an audience, that’s fine. You learned something, and you’re closer to finding a different idea that does work. The key point is “learned something” — not “fetishized failure.”
Making money as a magician is good. You can use the money to buy cheap coffee, or expensive coffee, or to buy a mansion with a big statue of Houdini — depending on how successful you are.
Here’s the thing: Being a magician is hard. When I said that, did you believe it? Ha.
