I’ve long advised guys to achieve mastery in something and instruct in it. When you start teaching students in something, you see the initial phases that used to freak you out for the small starting steps they are. Then you just mentally copy that feeling of being in charge, in command, over to your private life and act the same. 

It tends to come w/ experience, where you’ve seen things before and no  longer freak at novel situations. But you can fake your way there. LARPing is just the forced, knowing act of pretending your way towards something. People LARP in every career, just unknowingly, nitting the fibers of their persona over and over until they one day wake up and realize they ARE what they wanted to be once upon a time.
