Dude you made me laugh so hard I spilled coffee on my microscope. So you've been pushing foodcart, paperwork, or running errands for secretaries and this was the 'final assurance'???
It's darn hard to get the feeling of what being a doctor is like by watching... 'Shadowing' and whatnot is like sitting in your apartment watching a war movie... while BEING a doctor is like holding a gun and going to the battle.
Do the following: BEFORE you decide to do medicine, make friends with a resident or fellow. Surgery or IM are your best bets. Ask them if you can 'shadow' them... BY THAT I MEAN LITERALLY SHADOW THEM FOR A MONTH. They wake up by 2 AM to answer a page, you do the same. They go without food or sleep, you do the same. They give up family or social events, you do the same. Do it for a month or two at least. Experience what it's like to work whole night REALLY HARD, and then be crapped on by your attendings during morning rounds. Experience what it's like to deal with ungrateful, entitled patients. Smell the feces, urine, vomit and blood that will come in contact with your exposed skin. Try to FEEL THE CONSTANT FEAR of a lawsuit, which could make you loose EVERYTHING YOU WORKED FOR.
DON'T USE THIS EXPERIENCE TO PAD YOUR APPLICATION. Use this to TRULY ask yourself if this is the life you want to live. Then come back and report.
Oh I forgot. Also, try to IMAGINE, that while you are doing this, your debt worth hundreds of thousands of dollars is growing at 6+% annual rate.
