The aim of such an essay is obvious: you need it to convince admissions officers to accept you into college. As a rule, there is a word limit specified in the instruction for applicants.

In addition, the essay is aimed at portraying you as a personality, not as a professional.
"Most people don’t think of spiders when they bite into a tomato, but I do. Growing up in southern Ohio, I spent many summer afternoons picking baskets of tomatoes that would be canned or frozen and preserved for cold winter’s dinners. I loved the results of my labors, but I’ll never forget the sight of the enormous, black and white, scary-looking spiders that lived in the plants and created zigzag designs on their webs. In fact, those spiders, with their artistic web creations, inspired my interest in bugs and shaped my career in science."
Also, it’s important to know who you’re writing your life story for. Writing for your family and friends is great! But it requires a different perspective than writing for publication.

The goal is to help readers understand how events, hardships and experiences have molded you into the person you are today.
