I've posted this before, but I've had numerous admissions officers tell me "Well rounded applicants roll off the final admissions table." They'd rather see a dedicated drama kid who went all in and can speak interestingly and eloquently to that passion, than East Coast Becky, who was cheerleader, soccer captain, student body vice president, soup kitchen maven, and leader of the church choir. I had a friend whose school mate did admissions at Princeton and one year they let all the qualified tuba players in, because the marching band graduated a bunch of tuba players. Grades and test scores are likely all sparkling at a certain level of ranked school and above, so they want to get to know you through the application as a human and not a perfectly curated applicant.
Let your kid be a kid. When they get to 7th and 8th grade, if they organically develop a passion for something, encourage it. Then develop a Deep Safety, Safety, Match, Reach, and Lottery school list, cross reference it to cost, apply early.
