I like how you aren't limiting yourself to things and striving for the best in life.
This is a really thoughtful sentence. Because we do live in a world where perfection is basically impossible, it's still nice to see that people still have the will power to improve themselves and the world around them. I like how you don't limit it to just you as a person, and go further by saying this about you in your career.
I like depth of you sentence. It shows you really put some thought into it and did not carelessly say anything. I can see this in you and how it relates. You are very driven and it shows in class, heck, it shows in general since you were sponsored for skateboarding. And getting a place in the Guinness Book of World Records.
I enjoyed reading your sentence, and I also enjoyed the way it provoked a conversation between classmates. That's what good writing does and it's great to witness.
