<p>I would cut down on the number of activities and focus on developing your leadership roles and increasing your proficiency in a select few roles. For example: becoming a better debater and entering (and winning) higher-level debate competitions.</p>
<p>Don’t spread yourself too thin. This is relevant because you won’t be able to fit some of your activities on your college applications (most of them, including the Common App, restrict the number of activities you can put down), and your essays can’t refer to more than a handful of them as well. So the details that really matter are the depth and scope of your high-profile activities. It looks like music might be one of them, although as an Asian student, you need to balance that with a non-stereotypical activity as you write the “deep dive” essay(s) for your Columbia application.</p>
<p>Best of luck to you in the next few months!</p>
