I wanted to stand out
You stand out because of good writing. The content includes no spectacularly novel ideas, but it is very well written. The abruptnes you mention is hard to avoid when they impose a limit of 150 words, and actually, abrupt writing is awesome!! Many of the most popular writers are very abrupt, and it captures people's attention.
but I'm trying to play soccer in college, so I decided I best put it in there somewhere.
Do you really think the admissions essay will influence your chances of making the team? I don't really think it matters, but I could be wrong.
Most importantly, be confident, because you did very well with this, and it contains real energy that most writing lacks. I think it is a winning essay!
Michael may be right about the contractions. It depends on the reader's ideas... it may or may not be safe to use them. I think, however, that it is okay to say "soccer, for me, ... "---- because you are expressing something particular to you.
One more thing: Hey Michael!! Good call... the ending is not worthy of the rest of the essay! The ending could be more original and pack a harder punch.
