I was thinking of writing my PS on my intellectual curiosity (very interested in doing math in early ages because it was "puzzles" to solve, then I was interested in the human condition, became a psych major; however I wasnt really satisfied with math and psych because even though I grasped some fundamental concepts of the human condition and fulfilled my curosity, it didnt fulfill my want to leave an impact in the world, so I thought of taking law courses in UG; I enjoyed my law courses at UG, loved the complexity of cases and chances of making a real difference in the world)-> perhaps a bit idealistic.
This would not make a strong PS, in my opinion. It's very vague, and it's imparting a characteristic to you that everyone who is going to law school is just assumed to have.
It's also scattershot - you're all over the place. There's no possible way you can write anything in-depth or compelling about all of those facets of your life in two pages, double-spaced. The PS should be a laser, not a shotgun.
Pick one thing in your life that had a lasting impact on you, and write on that. It will be a much stronger statement.
