As any younger brother will tell you，having a big brother involves a lot of walking in someone else's shadow，especially when you have a brother who is a typical example of "cool"．For years I wanted to do everything my elder brother Tyson did，but no matter how hard I tried，I was always the neglected （被忽略的） one．My legs just weren't made to run like his．I could never play football or basketball well．

   I probably would have continued trying to keep up with him for the rest of my high school career，but when my family moved，everything changed．Tyson left for college，so I had to start at a new school all by myself．This new start gave me an opportunity to redefine myself and discover an entirely new version of "cool"．

    I don't know what made me decide to try some new activities at the new school，but one day I chanced to show up for an after﹣school meeting of the Science Olympiad team．I had always been fascinated with chemistry，biology，and math，but since those interests hadn't fit．Tyson's definition of "cool"，I had never pursued them．On this day，for some reason，I did．

    As we organized teams，prepared resources and practiced answering questions，I felt more connected than I ever had to any sports team．I didn't feel as though I needed to keep up with anybody else；I was finally with peers who understood me．It was so good to feel accepted for what I'm good at．For the first time in my life，I actually felt cool．Now I know who I am！I'm Tyson's little brother，but that's only part of my identity．I'm a cool guy in my own way，too．I'm relieved to know that "cool" has a much broader definition than what I used to think．
