Undergraduate / Dental hygiene application essay brainstorming [3]

my journey and passion to become a dental hygienist

Hi everyone,
This is my first post on here so I apologize if I'm not posting in the correct format, please bare with me! :)
I am going to be applying to dental hygiene school about a month from now and I'm going to begin writing my essay, but I'm feeling stuck on what to write about. I've never really been great at writing and putting the words I'm thinking onto paper. The prompt says, "Discuss any special abilities or skills that you believe would make you an asset to this profession". I spoke to many students who are currently in the program and they suggested that I write about my journey and passion to become a dental hygienist. I was thinking about starting off writing about my high school experience. I had no idea what I wanted to do with life and was very unmotivated to the point where my lowest GPA was a 1.8 (yikes, I know). But as soon as I discovered that my passion was to become a dental hygienist after getting my braces on and becoming very fixated on my own personal hygiene, I immediately did a 180° and became super determined. From that point on, I never got anything below a 4.0. Then I was going to go on and discuss my college journey - briefly touch on being a first generation college student and how that shaped me, further paint a picture of how hard I have been working for the past two years on prereqs, why I love dental hygiene, why I want to be apart of their program, etc. My question here really is, should I leave out the part about having a 1.8 GPA in high school? I'm not sure if it will lean more towards making me look terrible or really impressive since I found my passion and skyrocketed from there. What do you guys think about the other things I want to discuss as well? Thank you all in advance! :)
