Why one wants to be a physician. Claiming you'll be a good physician comes off as arrogant hogwash, don't do it- you aren't God's gift to the profession, and if you think you are, you're probably wrong. You don't know what it takes to be a good physician, nor what it means to be a good physician, until you're actually a physician- I don't even know what it takes to be a good doc as a medical student and person with many prior years in healthcare, it's still coming together. What you want is more tangible, what you will become is part of the journey. Focus on the tangible.
