Hey Andrew.
First of all, keep in mind that when Ozzi started his training he was.. 27 I think. Maybe 28. He's an ooldd man.
It's really simple. Like anything, theres advantages and disadvantages, as seen earlier in this topic. Younger kids learn quicker and are more flexible and have more mental plasticity, making learning easier for them. However, they (generally) have less life experience. They haven't had the time to participate in other skills that help build on Parkour. For example, Ozzi did some tumbling, breakdance, martial arts, and all that allowed him to get where he is now in what, two years, barely. Naturally, you've got some additional wisdom.
Overall, it comes back to being individual and seeing it as your path. Its hard to look around, for sure. I mean, it happens to me too. I'm a young 18 year old doing double kongs to you, but I look at my class, see 12 year old McKenzie doing perfect frontflips and vaults and rolls with no previous training and 3 months of Parkour training, and I'm now in the same spot as you. Just gotta find a way to rejoice it, and defeat that natural competitive nature we have, especially as guys. Like Leon said, some people just learn naturally fast. Gotta find a way to love that. Not easy.
But keep it up. If it makes you feel better, you guys really surprised me. As I said before, you guys were really fast learners, I was sincerely impressed, and really hope to get the chance to work with you all some more.
