Keep in mind, players can view your application once you have submitted it. They're allowed to post feedback about it on your application, and give it a "+1" or a "-1" based on their own opinions of "Would you be a good addition to the staff team?". All I'd suggest is focus on the requirements, and think "Why do you want to become staff" and it should come to you naturally if you're ready.
Best of luck if you decide to apply, but there's no harm in waiting it out!
