True story: so in high school I was friends with some guys who did parkour and they always had the weirdest motivations for training. When I first met them it was because they had heard about some scientist who escaped an erupting volcano by using his parkour skills. I have no idea if this was a real thing or not but they certainly believed it and saw it as a great motivation to learn parkour. Over time their motivation changed to various other things such as preparing for the zombie apocalypse. At one point at the end of high school they had a secret motivation that they didn't want to tell me about. It took a month but I finally got it out of them. They were planning to form a drug busting team to use their parkour skills to break into drug dealers houses and steal their cash to donate to charity. They were dead serious about this. When I asked why they wouldn't just report the dealers to the police, they said because they smoke too much weed and might get arrested. So instead they wanted to be 21st century Robin Hoods. Fortunately for everybody they never managed to find any drug dealers and eventually outgrew that idea.
