Essentially, everyone else has covered what you need to think about. I've attached a copy of ours for an example.
Everything is going to be okay. Just speak your heart in the essay. Make sure you outlined the topics and make sure you demonstrate how you ware unique. Provide special emphasis on the really unique aspects, even if they are small.
Also, might not hurt to create a "judging sheet" based off of the Chairmans outline, and have people outside FIRST read it and judge it. (ex. "Clearly outlines how they are a role model for other teams to emulate. Circle 1 2 3 4 5... etc.)
If there's anything else you need help with Chairmans-wise, feel free to email me at
alexkstout@gmail.com .I am a Chairmans leader on my team, so we can answer any questions you may have.
Good luck and I hope this helps.
