Enjoy your youth, and spryness. As you get older you will lose balance and things like skateboarding will get harder.
A few years ago my son was planning to spend part of a summer working on his skills, then he spied a bmx park, got into that, and took state for his age group! His rationalization to me for the expence was that the kids that did bmx did less drugs! HA boy did he have a line.....
I know though that any good healthy sport grows strength in character as well as body. So, enjoy it and help others master those tricks and it is all good.
