So I can use the same ps for law school, clown college, and "Why I deserve to be an Avon representative." essay contest?
I'm not saying the entire statement should be about law school, but at the very least there should be an explanation about why the things you've mentioned are pertinent to law school. And if, as I can already hear you saying, those things are self-explanatory, then you should rewrite your ps so that it's not so quotidian. Anyone who applies to law school can probably think well in a straightforward manner. They want to see what sets you apart from the crowd. A lackluster ps is just going to lump you in with the masses.
You have to write with a purpose. The purpose of a ps is to get into law school. Period. Talking about sports, your dead grandmother, or how you raise orangutangs in the wild is only going to help if you connect it with your worth to the law school. Adcomms do have souls, but they're not paid to admit applicants who can simply brag about themselves and make people cry... you have to tell them how you would contribute to the school.
