I have 500 characters to describe a time I fell short. I planned to talk about my extreme shyness. This is just a summary of my situation and will write a 2000 character essay about how I overcame it later.
A major step in my life was starting high school; I didn't how to act, where to sit, or who to talk to. I would become light-headed contemplating every move, outfit, and hairstyle. The first week of school, I was chosen to read a paragraph in the disclosure document, I would begin to sweat and stutter every other word. I would feel a sigh of relief when it was over. I knew I couldn't keep this up for three years and that something needed to change.
The next section I will write about how I overcame this.
Is this a good description of my situation? Any grammar errors, etc?
