It is important to put yourself in the shoes of the Admissions Officer: why would your personal statement be unique, how are you different from the other candidates? Primarily you need to decide how you will divide your personal statement into digestible chucks. The most obvious way is to divide into paragraphs of 100 words. If you aim for between 500 and 600 words at most, it will help your admission officer when they have to read thousands of personal statements to find the perfect student.
This is why so many people choose to opt for help in writing their personal statement for college. For me, it was easy. My mother was an award winning writer, and I could ask her for her feedback any time I wanted (I still can, as a matter of fact) and as often as I want to. Although we don't always see agree, her invaluable input is always intelligent and well thought out. She helped me a lot on my personal statement for college, as well as my essays. But for people who don't have that kind of resource at their easy disposal, or a high school English teacher whose opinion they value, there are many sites and resources all over the internet which can help them to write a personal statement for college professionally. These can give feedback, editing, and can even give you templates and tips advising you the most common things to avoid, and the most important things to do when writing your personal statement for college. In my opinion, though, there is no real alternative to personal, face to face feedback from someone whom you trust on your personal statement for college write up. It is not easy to write a professional personal statement. Most of us struggle with the writing.
