Being an Apologist _ You do not use your personal statement to explain why you lack certain skills or experience. The point of writing this short paragraph is to sell yourself and this involves highlighting your strengths instead of apologizing for your weaknesses which in itself is a sign of weakness. The time and place for discussing flaws in your suitability is the interview and at that point, you must focus on how you plan to overcome any holes in experience/skills etc.
Using plagiarized content _ Personal statement examples can serve as excellent guides when it comes to writing your personal essays. However, using the actual content of these samples and passing them off as your own is one surefire way to jeopardize your statement. Plagiarizing other people's work so that your personal essay appears highly interesting is a sign of incompetence and irresponsibility. Surely, you would not want to communicate these poor qualities to the selections committee. If you must, make use of personal statement examples, you need to use them only as guides. You can use the outline as a sample, so you will know which experiences to include in your essay and which ones to leave out.
