<p>I think it is a great essay topic. </p>
<p>The only thing I would be careful about is to make it sound genuine. By your post, it seems like it really meant alot to you, but make sure you convey that. The only thing I'd fear is that, if it isn't written well, the topic might seem to be too superficial or big, and it might seem you choose such a big theme to impress them rather than it truly coming from yourself. Again, its an excellent topic, but it's all about the way you present it.</p>
