At first I found why I could not keep my balances on a board easily. And it seemed almost possibly for me to go any distance without falling. I hated to fail in any sport, so I continued to try and finally manage to go all the way up a slope (斜坡) without an accident. It was then when I realized what a great sport it was. Now I'd rather going snowboarding regularly.

    I once get a VIP pass to a huge concert given by one of the most popular rock bands in world. The ticket qualified me to meet all the member of the band backstage but to watch the whole process of setting up for the concert. The guitarist was a man whom was very kind. I did not have much anxiety while getting to know them better, but the rest were more of reserved. They just smiled and made friend gestures. Anyway, watching the stage being set up and all the microphones being checking, I understood how hard it was to putting on a stadium concert. It took hours of preparation to produce quality sound.
