Overcoming challenges - English

I sit at my desk, staring blankly at the smooth wood surface. I replay the question over and over in my head, searching my memories trying to remember something. What challenge have I overcome, worthy of writing about? It's not often I step outside my safety bubble, and when I do I run back to it like a small child running back to it's parent after school. A pit forms in my stomach. Am I really that boring that I have nothing to write about? Do I seriously lack that much experience that I can't think of one little challenge I've over come, in fourteen years have I done anything? I run my fingers over the surface in front of me, hoping that if I concentrate enough something will come to me. This thinking process might be in itself the biggest challenge I've over come. That's when I got my million dollar idea. I grabbed my purple computer out of my grey school bag, and start writing.
