Need Advice on Writing a Statement of Purpose

Hey everyone! So, I'm in the middle of working on my statement of purpose for a grad school application, and wow, it’s way harder than I expected. I remember writing something similar during undergrad, but it was just a personal essay—this feels like it has to be way more polished. I really want it to reflect why I'm passionate about my field, but I'm struggling with how to make it sound genuine and not just a list of achievements. Any advice on how to balance being professional with showing personality? Thanks a ton!
