overselling a theme?

<p>How do I know if I'm overselling a theme? For example, I was in learning disorder classes K-5, and I think I can branch everything off of that. Starting a new theme half way through the essay would disrupt the flow. I don't want admissions to think I'm fixated on one achievement. Casually mentioning it would leave a lot of questions to be asked, and may hurt me. So I get the feeling that I either have to think of a new theme, or focus on this one. Because UChicago has multiple essays, I suppose I could make it the theme in one, and not the other. What do you think?</p>
