What @TiggerDad mentioned as nurtured hooks are actually referred to as a spike, which is something you’re extremely strong and talented in (Olympics, Carnegie Hall, famous publisher, etc.). Hooks are more things to consider from the applicant’s personal situation and/or background. Hooks are much more personal and situational, and usually involves with someone advocating for you to the admissions officers (coach, legacy parent, a professor who’s your dad, etc.) while spikes are more on the talent and passion side of things.
