“Show, not just tell.” It means you don’t just explain an interest or hardships. Or just say you’ll do X. You need to include examples that show strengths they look for, for their campus community. So, first you need an idea of what traits matter to them. And these need to be relevant to campus life.
You won’t be taking your birds to college. They aren’t looking for “uniqueness” as much as how you actually fit- a sort of conformity. If you write about a job it should “show” how you grew and came to impact others, not just at work. The adcoms should be able to feel this and agree, as they read, (not just have to take your statementas at face value) and see how you fit at ther colleges, will be an asset. You want to be cautious about basing this on prior poor social skills. And it can be an issue to say scoring created an interest. The higher the tier, the more they want to know it wasn’t just scores or grades (not, Hey, I got an A and got interested.)
Easiest is to pick a challenge you overcame. Just enough to describe it, then how you evolved, what you’re now involved with that demonstates a turn around or growth. And remember, relevant.
