I’m aiming for UCSD and UCLA but I feel this topic might be to generic, I was planning to talk about all the things I’m juggling right now which include wrestling, 2 AP math classes, marching band, being a club leader, and being a big brother for 4 siblings including a 2 month old and how I’m handling it well and realize my priorities instead of hanging out with my friends I focus on school and how this would make me a good college student…etc.
I’m no expert but that seems like a lot of information to put in one essay. I would focus on one thing, like being a big brother, and talk about how much it has affected you throughout high school.
The issue that I see with this is that every high schooler is busy; this isn’t a challenge that is unique to you, nor will reflect your specific personality well. I agree with @serignediaw - pick something specific that YOU feel is meaningful to you, and “write the essay only you can write.”
