“Mama, when I grow up, I’m going to be one of those!” I said this after seeing the Capital Dancing Company perform when I was three. It was the first time that my __36__ took on a vivid form and acted as something important to start my training. As I grew older and was __37__ to more, my interests in the world of dance __38__ varied but that little girl’s dream of someday becoming a __39__ in the company never left me. In the summer of 2005 when I was 18, I received the phone call which made that dream a __40__; I became a member of the company __41__ back to 1925.

I never actually __44__ to get the job. After being offered the position, I was completely __45__. I remember shaking with excitement.
Though I was absolutely thrilled with the chance, it did not come without its fair share of __46__. Through the strict rehearsal period of dancing six days a week, I found it vital to __47__ up the material fast with every last bit of concentration. It is that extreme __48__ to detail (细节) and stress on practice that set us __49__.

I learned to make each performance better than the last.
Today, when I look at the unbelievable company that I have the great __54__ of being a part of, not only as a member, but as a dance captain, I see a __55__ that has inspired not only generations of little girls but a splendid company that continues to develop and grow-and inspires people every day to follow their dreams.
