The introduction _ This may sound strange but saving the introduction for last is more advantageous than it may seem. Having written the body and the conclusion, you are now in the best position to tell the reader, as creatively as possible, what they are reading into. In the introduction, explain your thesis statement and how you are going to affirm it without being too specific. Do not use typical introductions such as"This essay is about..." or "The topic of this essay is..." or "I will now show that..." It is not only boring but also uncreative.
Keep It Readable _ You will also want to keep your personal statement/essay to a readable length and writing style. Trying to use large words and convoluted sentences to make the personal sound more impressive will only lead the reader to put the paper down.
