Your personal statement should be about who you are -- by that I mean what individualizes you from other applicants. A list of your honors and awards is less useful to admissions committees than an explanation of why you were motivated to achieve those honors and awards. Write about who or what inspires you, and about who you are.
To make it interesting to read, begin with an attention-grabbing lead--an anecdote, question, or engaging description of a scene. Use personal examples to show, not just tell, the admissions committee about yourself. End your essay with a conclusion that refers back to the lead and restates your thesis.

I know that the whole thing is easier said than done. Expect to write and revise your essay a number of times, ask 2 or 3 people whose writing expertise you trust to review it, and read it aloud to see if you like how it sounds.
Best of luck with it!
