What is somthing interesting i can do to write on my personal statement?

i have this summer then i need to start writing my personal statement for universtiy so im trying to do as many different and interesting things to really stand out from the crowd, since everyone elses personal statement seems same old, ive recently become a samaritan listener with the helplines and i have linked up with a penpal on death row usa. i really want to stand out and be tottally unique. any ideas?
