Can you help me to write professionally a paragraph in my cover letter
this is my paragraph
I’m eager for knowledge and art, my future wish is to get X price, I know it needs a hard work, but your own qualification for me to do a Ph.D. in your university is a first and great step to get my wish.

Question

Answer

I am passionate about knowledge and art, my future wish is to get X price, which I know requires hard work, but a Ph.D. from your university is a first and great step towards achieving my goals.

Not sure what you mean by "price" but if you can let me know I can suggest another word.  Price, probably isn't it for a cover letter.
