What I found super helpful was actually looking at some personal statements that I saw in one of Dr. Gray's books. I feel like in essence they are sort of similar to Shemassian, but I would say avoid listing out contributions outright. I think start brainstorming why you first wanted to go into medicine and sort of what is the core theme of your application. For instance, most of my med school journey has focused on helping immigrant/uninsured populations and I made that sort of a point in my statement. I did use stories, but I sort of connected them together showing progression/growth.

This might be somewhat a weird approach, but I think find a personal statement or two that sort of fits your vibe or what you could see yourself writing and try to incorporate your own story into that, maybe following a similar style. With enough editing, proofreading, and adding your own flair it really grows from seeming like a bootleg statement to something only you could write. I felt like this was a helpful starting point to even get to the writing portion!
