Understanding the commitment

Its only been a few days since I started IHC, but I'm already starting to figure out its a lot more then I was expecting. Even after just a few days, my shoulders are starting to hurt and my body is constantly telling me "What were you thinking!?!", but my mind is telling me joining the team is the best decision I've made in a long time. Kung fu has been a big part of my life now, and I like it that way. Constantly dropping to the ground to do push ups from the moment you wake up to the moment you fall asleep is really making me feel positively better about myself, giving me the "You can do it!" feeling. While this commitment is pushing out the unnecessary things in life like video games, it makes me wonder on the inside: What if I didn't start IHC? Would I still be the person I was?
