At this point, I’m not sure what more we can say. The brightest applicants “get it.” They can climb out of their own heads, their own high school thinking, those limits. It shows in their choices. And those choices go beyond just what “interests” them or their own future career ideas.
Of course, one can add an activity in junior year or this summer.
More to say, but OP’s either going to get it or not. Imo, he needs to expand his thinking, be that sort. Or not. Right now, that’s on him, how he understands and proceeds.
