This is for anesthesiologists only. i am a 21 yr guy about to start my undergraduate. ?

What classes should i focus on? Also is it necessary for me to do community service at a hospital? Im currently a CNA so I'm fairly accustomed to patient care. Also I have a one yr old daughter, has anyone else attempted this goal while being a parent? I do know that i want this more than i want air to breathe. And I am very determined, just wanted a little of advice from people with some know how.
