Which essay should I send?

<p>I have written one about physics which adds some passion to my application that my ECs do not reveal. I am writing another one about how I helped supplement my family's income, but only half way through.
Do you think I should submit the physics one which I have revised 20 times and is near perfect now, or wait till I finish the other one? Deadline is approaching!!!</p>

<p>Which one will be the most personal, detailed, honest and revealing?</p>
