Rewording and shortening a Yale Short Take

I'm an international student and I have given an answer to a question in Yale's Supplement but I feel that it does not sound American. Could anyone please help me to reword/rephrase it in order to get a nicer and a SHORTER sentence? Must be 25 words or fewer! (Now it is 28)

What do you wish you were better at being or doing?

My answer: My friends often laugh at me when I tell them a story for the umpteen time. I wish I could remember exactly what I have already told them.

I would appreciate your kind reply as soon as possible as the application deadline is Dec. 31...
Also, if you feel that my response (overall) isn't good enough, please let me know!

isn't the deadline jan 1?

please take a look at my common app essay. deadline is tom.

Thank you for shortening my sentence. For Yale the deadline is Dec. 31. But yes, for most schools its Jan. 1.
I would just need a quick response from any Americans: isn't the word "umpteen" too awkward?

umpteen isnt too awkward but it should be umpteenth

please critique my nyu supplement if you have time :)
