Answer: I believe the answer is 1 or 3. Most likely to be 1 though.
Explanation: My reasoning is that what everyone thinks of you does not help you show credibility when writing persuasive essays. Your feelings and opinions might not be enough to persuade anyone and it shows no credibility. Advice from strangers also shows no credibility and no one will be persuade anybody with common sense while personal experience on the other hand, shows credibility and it is most likely to persuade many people.
