In talking to Admissions Representatives across the country, there is one aspect of a personal statement they all agree on _ BE YOURSELF and let them get a feel for the type of person you really are. This includes your motivations and the ability to evaluate your personal experiences and the effect they had on you. If you can understand that 8 out of 10 personal statements fail to do this, then you are well on your way to being 1 of the 2 applicants in every 10 that stands out.
When you set to create your personal statement for college, you suddenly are not in that world anymore, and you know it deep inside. Seriously, no one from admissions wants to read another essay about how much someone was inspired by Gandhi, or Martin Luther King Jr. No one wants to read your personal statement for college about the first time you played football with your dad, or learning the value of teamwork from a little league game. No matter what you write, the chance is that they have heard it all so often before, and they are surely going to hold that fact against you.
