College Essay Topics

Hi! I decided to completely rewrite my essay because at the end of the day, I was not passionate about it. I wanted to get your opinions on my topic.
I first wrote about theater and how passionate I was about it (not really).
I really love children, considering I work with them. I was going to include it in my “interests”, because I wanted to write about how its important to protect the youth and I want to be a pediatrician.
My second topic is how I scrubbed into a surgery for the first time, and I knew how that was what I wanted to do, and how important the medical field is, but once again, I have to develop it.
My third topic might be was going to be mental health, more focused on anxiety. How it isn’t my identity, but something I’m growing from and learning everyday. However, I know this could be perceived as basic.

Scrubbing in for surgery caught my attention. I don’t know any teens who have done that!

It’s not about “passion.”
Nor explaining your career interests.

Elaborate. I’m focusing on ApplyTexas prompt of “Most students have an identity, an interest, or a talent that defines them in an essential way. Tell us
about yourself.” I was going to write about LGBT, but that was not recommended by anyone here. So please, give more insight.
