Focusing on negativity _ People face problems from time to time; however, there are those who have faced graver trials than others. If you are one of those people who's had your fair share of problems, make sure that you adopt a positive attitude despite the challenges, and reflect this attitude in your statement. Wallowing in negativity will give off an unfavorable vibe, and enumerating all the trials you've been through will no longer make your essay an interesting read.
7. Say something potentially offensiv _ Again, not much explanation needed on this one. You do not know anything about the people who are reading your personal statement. Assume they are very sensitive on all issues and write accordingly. Do not assume they agree with any of your political, social, or religious views.
