I'm a 2nd year medical student, so I guess I can't build an opinion on my own experience, since It's just starting, but I still felt pretty pissed off to see all those residents and attendings talking so bad about the profesion they're chosen, lime it was some sort of mistake...it is not for a few reasons:
1- Med school does not take away the best years of ones life, remember than you only need ONE night to get drunk, get laid or party, you don't need an empty schedule to have a moment of pleassure, don't tell me you didn't took a trip on a spring break or something like that becuase it is just not true, and please don't come saying "You are only a 2nd year student who doesn't know the meaning of studying and hard work" because I actually have studied 12 hours a day myself, missed a lot of parties and night-outs, but you have to realize that you don't need them ALL, just remember that when you get your chance to party, stay till the last second, be the more wasted person out there, make it worth.
2-You all say that this whole effort it's not worthed, but this is what you choosed and you did it for a reason, what does worthed means? to choose an easier profesion in which one starts making money earlier and has more time to party? what are you gonna do with the REST OF YOUR LIFE if you choose a carrer like that? We work more that 8 hours a day to bring the bacon, we are all individuals and not walking diplomas, that's true, but if I have to choose a way to make a living, it better be something I enjoy. Think about the future, do you really want to wake up all the mornings and go to work to a bank??? or a law firm??? Give me a break!! That would make me sick.
3-You don't get into medicine for economic compensation or patient's grattitude, the economic situation can change dramatically and patients can be very ungrateful, you get into medicine for medicine itself, for what it is, for anatomy, physiology, pathology, etc. That's a reason that will NEVER die when you love the thing itself and not what it brings you, that's when you gotta be a doctor.
4-What other carrer will give you such intense experiences? When you all came back talking all excited about your first rotation, what were your friends in MBA talking about? Memmos, probably...

...I don't really know and I don't care.
5-What other carrer will give you the posibility to practice and teach and the same time as in medicine?
6-In medicine everything so concrete and definitive that every day you know you're learning something, you ca actually point it with your finger, in other carrers you progress too, but you don't have the environment yo realize it EVERY day, it's just a different kind of progress.
That's just my opinion and Im sure I won't change my mind and won't regret it, I still have time to quit but I just won't do it.
For those who had a bad experience, whatever the reason was, Im sorry for you, I just hope you don't feel sorry for yourselves because to me, you are doctors, as a 2nd year student I must say I really respect you.
NO ME ARREPIENTO DE ESTE AMOR, AUNQUE ME CUESTE EL CORAZON.
