Scholarship / "to expand my knowledge basis" - Why do you desire to attend college? [3]

I'm not a great writer and any suggestions or changes are greatly appreciated. Why do you desire to attend college? (Short 3-4 Sentences)

College is something that I have always wanted to attend. My desire comes from my love of learning, which might sound cheesy, but I honestly have always wanted to expand my knowledge basis. My motivation also comes from my family. I have a great support system in place, with a mom, dad, and sister that have always helped me pursue my dreams. Finally, I want to be a doctor to understand why I lost my grandpa and maybe in the future make a difference in cancer research.
