Parkour!

Parkour is an interesting sport, I would say that its a bit like... urban gymnastics. ITs the art of spatial awareness, its observing one's surroundings and learning how to move through them, its a discipline, a philosophy and its really, really fun.
Now I stared parkour only  two days ago  so I don't have much experience, but what I have learned is wonderful. We are taught to trust our instincts as much as we trust what we are taught. It turns out, your body can do a lot more than you thought it could. First we learned basic jumps. Up, down, you learn that jumping from higher areas means letting your legs absorb the shock, it also means that you roll. As you land you find that your body goes into a roll on its own, as if you'd always been prepared for it.
It can seem a bit overwhelming at first, to see those people flipping around and doing insane jumps as if they were nothing, but as it happens, anyone can do incredible things. For me just being able to jump from five feet after doing a terrible cartwheel is incredible. You begin slowly and you push your limits. Little by little you build up from a small hop to a long jump, you dare to move faster, you push yourself and that is intoxicating.
In whatever sport you choose, you test yourself. You start off as a small and wimpy noob and slowly build up. Whatever you do, don't let this intimidate you. No matter who you are with, they had to start somewhere, they were once as new and lost as you.  so go out, try something, learn, evolve and move.
