2. BE POSITIVE. Your statement should not sound staged or stilted, but enthusiastic and motivated. Consider topics which would be easiest for you to put descriptive words to. Your personal statement is a testament of your passions and your earnestness, the image you want the reviewing committee to see of you. That image should never be negative, bland, or boring; you want the committee to say, on reading your statement, we'd like to meet this person. Avoid using "waffle" words (words which qualify your experiences and commitment) such as "rather", "quite", "somewhat", or "probably". Waffle words tend to give the impression the writer is unsure of him or herself; with the personal statement, all writing should be positive and express confidence and directness.
10. Use poor spelling or poor grammar _ This one should be pretty obvious. Academics on admissions committees are generally high achievers with high standards who won't disregard even simple typos. If your personal statement is not technically perfect, it can make you seem sloppy, lazy, or inattentive, which are not qualities anyone wants in a future colleague. Remember that the people skimming your essay are seeking a reason to reject your application and make the pile of possible admits smaller. Always get someone with strong writing skills to review your essay.
