Ny number one extracurricular on my common app is my YouTube channel. I know a lot of people think this is risky, so I just wanted to know how it sounded from an objective perspective.
Since May of this year, I’ve acquired 110,000 subscribers, 7 million total views, and it’s my job. I post educational content regarding motion graphic editing + other fun editing related content. It’s something I’m extremely passionate about, and I also linked my channel in additional information. I’m still very nervous about it because I don’t know if it’s impressive or seems odd.
Congrats on what sounds like a super successful channel! I think it can’t hurt you if its something you spent a lot of time on and are genuinely passionate about 
Don’t want to make you overthink since this is totally an okay thing in my opinion but it might be even better if you have connections to this passion in an essay or if it’s connected to your major in any way! Overall, don’t overthink it since it’s definitely impressive- also since you have 10 activities, just make sure you’re ranking the rest accordingly!
Sure, I don’t see why not.
