Scholarship essays are personal in nature. You are putting yourself out there and sharing your goals and experience.
However, be sure you also keep it professional in tone. Do not use slang terms, or a lot of contractions. Essays are more polished when you can write out the words for contractions. At times, it may not make sense, but whenever possible, follow this policy.
As you write, think about who will be reading it. Write it as if you are addressing someone familiar to you, someone you respect, and someone you want to share your story with. This may help to put you in the right frame of mind and helps to identify an audience.
