I would suggest that you avoid writing a lofty, esoteric personal statement. Instead focus on who you are. The purpose of the personal statement is to give the law school insight into you as a person, in a way that your numbers alone cannot reveal. Schools frequently impose word limits on the personal statement. Even if the school does not have a limit on length, you should limit your personal statement to two pages.
Using anecdotes and even allegory can be useful literary devices. You should write a personal statement that you would want to read, and stories are often the most interesting reading. Humor can also be appropriate, however, be careful not to sound silly or immature. Tell the admissions decision makers about you. Everyone has an interesting anecdote about himself or herself. However, it is difficult for many of us to see the interest value in our own stories. It might be of benefit to consult with your friends and family, who may be an objective source of anecdotal ideas. Now is not the time to be shy and self-effacing. However, it is equally not the time to boast indiscriminately.
Stories about overcoming hardship and adversity are interesting because they give admissions committees insight into your character. Stories which describe lessons learned are equally interesting because they provide a glimpse into how you think and grow. By the same token, a snapshot into your personality may also stand out and be an effective antidote to thousands of personal statements, written by students who take themselves too seriously. Be creative, be different, and be interesting.
Review and revise your personal statement until it is an interesting, tight read. Open with an attention-grabbing premise and keep the reader interested with insight into your personality. As you draft and redraft the statement, eliminate redundancy and excess verbiage. Use short sentences to add “punch” to your prose.
Remember that although a good personal statement may not get you into law school, a bad one will certainly keep you out. Simply write something interesting and informative, in a respectful and appropriate tone.
Finally, your personal statement should be perfect. There should be no grammatical errors, punctuation errors or typographical errors.
