There was never a moment where I consciously told myself, "Hey, I think it's about time I set myself apart from everyone in my major." It wasn't about that, and if you focus on that as your goal, you're doing it wrong.
I had a passion, a thirst for knowledge and a burning curiosity. Those traits led me to do interesting things with my college newspaper, lead interesting discussions in my classes, etc. By nature, I became a leader, and other inspired and eager people followed.
So don't worry so much about setting yourself apart. Just do what you love doing and always try to learn about how you can do that better. Then share that with everyone else.
