I believe my essays were critical. I spent dozens of hours brainstorming a compelling theme for my personal statement and avoided cliche topics like sports injuries or extended metaphors.
I recommend finding something you are genuinely interested in and committing to it rather than copying others. For me, it was building projects in my basement workshop; for others, it might be pottery or backpacking.
I focused on building strong relationships with a select few teachers starting in my sophomore or junior year. Simply getting a good grade isn't enough; you need to actively participate and talk to them about your life and interests.
I took 12 AP exams, which was too many and resulted in a lot of stress. You don't need to take every AP class just for the label; I believe I still would have been accepted into Stanford with half as many.
The most important thing is to not procrastinate. I set aside 30 minutes every day starting in September to work on essays, which allowed me to recycle and edit core pieces for different schools.
A major misconception is that the process is purely merit-based. It is much more random and nonsensical than people think, and the results are not a reflection of your self-worth as a human being.
