Immersing myself in this discipline has transformed my life completely. For one thing, I was something of a party animal before I had the sense of purpose that parkour provides. I was very unhealthy; I drank excessively, smoked and did harmful drugs, all of which have been left behind now. Parkour has also shifted the way I approach difficult things in my life. Rather than wilting in the face of challenge, as I had done previously, I now sprint toward it with a big smile and wide eyes.
