Writing Feedback / 'My lifetime goal was to attend an American university' - 2 sentences [2]

I feel like these two sentences do not flow and sound a little awkward when reading them.

Through my experiences that have been accumulated over the years combined with a tremendous amount of willpower and determination, I am willing to devote myself to my college community. My lifetime goal has always been to attend an American university and pursue a career in computer related major, and I hope that you will sincerely consider my request.
