Undergraduate / "a professional bass trombone player" - 2-3 paragraph essay for school of music [2]

so i'm really horrible at writing. i did total crap for the SAT's and even for the FCAT writes. I need major help. to be honest, I think I do good if I can even finish an essay in class.

i need to outline my major musical goals for this essay and this is what i have so far

I want to be a professional bass trombone player for my career. I want to one day be able to play in a major symphony or maybe record for a movie or even a television show. I want to be able to listen to a soundtrack, hear an amazing bass trombone sound and be able to say "yep, that's me!" to all my friends and family who watched the movie or listened to the soundtrack.

During my time as a professional musician, I would like to be a university professor and try to make each player better than I was and hopefully be able to see them as a better performer than I was. I want to be able to make a difference in the musical world even if it's just a small one.

some pointers on what to add or how expand what i already have would be seriously helpful. thanks!
