Essay Help!!

<p>For my college essay topic (Indicate a person who has had a significant influence on you, and describe that influence) I'm writing about how a doctor on discovery health channel influenced me/inspired me to work hard when i was younger. I'm also including how my opinion of the doctor later changed after learning about his DUI's, medical malpractice, etc. Also including how i learned not everything on tv is real/my naivety. My dad thinks i avoid writing about television and someone i haven't actually met as an influence. I value my dad's opinion, but i don't know if i should scrap it write and something new or just keep what i have... Any suggestions? Thanks!</p>
