"How?"
"Use a reference."
"What do you mean?"
"Trees. Colors. A smell. A memory. A sound. Exercise. A book. A film. A painting. Rubbing your hands. A shower. Pretty much anything goes. It all depends on you and how much work and time you want to and can put into it."
"I've tried. Doesn't take."
"Well, you haven't tried after what I've got to say."
"So say it."
"You're a conscious entity in a fluid and electrical biological body or machine. Any stimulation of this body triggers your power response, or ability, or skill. It's like a muscle you have to learn how to use and workout based on how it works. What you got, body or type, and who you are, your life, personality, individuality, character, and your genetic background will give you an idea on how you should go about it. Nevermind the fact that life—and your genetic code, by extension—is however many fucking billions of years old—without counting before it ever got to this planet or how, but let’s just start with what we got. If you really want to go crazy, it might take you reaching into the subatomic and cosmic scale of things. Your mind is the medium of the message. And if there’s no message, there’s no medium. I have no idea what to do about it if you don't have a body though. Ghosts aren't real."
"Seriously?"
"It's a work in progress."
"Fuck it. This is bullshit."
"So, what? Try everything?"
"No, you'd be dead before you got to the end. Like I said, start with your mind, body, and your life."
"OK. Now you're making sense."
"Oh, thanks. I try."
"How do you do yours?"
"The simpler and more basic the material, the more you've got to work with."
"Huh. You are a genius."
"I'd rather not live inside a bottle making other people's wishes come true."
"What if you lose control?"
"You ever shit your pants?"
"Good point."
