I am a medical student, trying hard to become a doctor.  As a future doctor, I feel like I have the responsibility to practice what I preach in terms of a healthy lifestyle.  Doctors tell their patients to lose weight and eat healthy, but many don't follow their own advice and I think that it doesn't help to motivate the patient in any way.  I can honestly say that I haven't had the most healthiest lifestyle, but I am willing to start now.  I promise to be healthy physically, mentally and emotionally.  Only then, would I feel comfortable enough to advise others on how to live.
