Replying to Realization

Today I was shredding my backyard ramp... And when I was feeling really stoked and like I was really awesome hitting my 15ft rail stomping every hit... Then something just happened. I dropped in like normal and jump off the ramp just like normal. Some how some way I got clipped or something in the oddest way possible.  I have fallen on it before but not like this, this time I flew forward and just belly flopped onto the rail and then slid of and got my gut hit on the 2x4 supports that hold the rail up. Instantly pain just filled my gut and arms... basically my arms and gut took the punch. I laid there gasping for breath like you do when your winded feeling like death was near... blah blah blah... And as I lay there I was like fuck this I quit. I quit I am finished hitting this rail for a month at least... then the pain succeeded... I felt this rush of realization. I am not awesome, I have much to learn, and if I am going to be any good at this amazing sport I must take the hits that it brings me. I got up to the top shaking, hit the rail just fine realizing... I am just lucky that I even get to ski. Let alone my backyard. Anyone else ever had any realizations like this that feel like they alter your life?
