How I chose which of my accomplishments to feature vs. mention briefly

Had more genuinely relevant accomplishments than I could give full, detailed treatment to in a reasonably-length personal statement, and had to make real choices about depth versus breadth. Sharing the principle that guided those choices. I gave full, detailed treatment to the 3-4 accomplishments doing the most work for my strongest criteria — enough specific detail to make them feel concrete and verifiable, not just asserted. Everything else genuinely relevant but less central got a brief, honest mention, often just a sentence, rather than either full treatment (which would have diluted focus) or complete omission (which would have understated my actual record). The mistake I initially made in an early draft: giving every accomplishment roughly equal, moderate treatment, which meant nothing got the depth needed to actually feel persuasive rather than just listed. Concentrating detail on the strongest few, while still acknowledging the rest briefly, made for a much more convincing document than spreading attention evenly.
