<p>Well, what I've learned reading so many essays is that although some topics are very common, the important thing is how you write it.
I think a non-mainstream sport like rock climbing could make you stand out, because it's different, but then again a boring essay about that would probably make not much difference.</p>
<p>I think I will just take a memorable experience I had in one of my ECs and elaborate on it. I don't know how much this helps, I don't really know about other people and would like to hear a few opinions as well.</p>
<p>And you're definitely right about the "This has taught me bla bla" part, a good essay should show not tell. :)</p>
<p>The best thing to write about would be something you're passionate about so that you could produce a fun, engaging essay. It doesn't matter what it is as long as it's going to be interesting to read and will show a side of you. If it's athletics, go for it.</p>
<p>on one app, i decided to elaborate on my number 1 choice of the previous form. But on another, i decided to use a more minor event (summer camp type deal) to explain another thing. I dunno if it's okay, but that's what I did.</p>
