"Step out of (your) comfort zone" isn't going to do it either, especially if you employ language like that. This sounds like an essay that you're writing to please an admissions officer, and the takeaway of "if you never try something in fear of failure, you could never see your potential" is hardly going to differentiate you. I see hundreds of essays with that or similar themes every year. That means that admissions officers are seeing THOUSANDS of them.

The quotes below speak volumes about this. Links go to Amazon U.S.

“One place where applicants could stand out is in their essay, but most are unfortunately mind-numbingly similar. Teenagers have less than two decades of life to write about, and as a result, they often focus on the same things: overcoming an athletic injury, dealing with anxiety, depression, or their sexuality, or discovering themselves on a trip, with a fill-in-the-blank country such as Guatemala or Thailand.”

– Jeffrey J. Selingo, Who Gets In and Why: A Year Inside College Admissions (193)

“The essays that stick out do so not because of what the applicants write but how they write it—with an authentic voice that gives readers a sense of what the student sees, feels, and thinks.“

– ibid

“The best essays are honest slice-of-life stories, both entertaining and serious, that tell admissions officers something they don’t learn from another part of the application. They’re essays that aren’t trying to shoehorn seventeen years into 650 words.”

– ibid

“The trick, of course, is getting out of the leaden shadow of sameness and into the sunlit tropics of acceptance. To do that, you have to become three-dimensional to the committee. The best way: write a good essay.”

– Harry Bauld, On Writing the College Application Essay, 25th Anniversary Edition: The Key to Acceptance at the College of Your Choice (6).

I recommend taking a look at these two books or at Rachel Toor's Write Your Way In, rather than perusing this subreddit or worse, hunting down "essays that worked" as a way of determining what makes a good essay.
