I've lost a lot of passion for medicine, and i'm not even a pre med. I talk more abut poltics and economics. But something just draws me to medicine. The science is stimulating, you having to know physiology, neuroscience and biology as well as how to treat a sick man is knowledge that can fill your brain for fifty lifetimes. Science is actually applied to make people cheat death. Medicine is life, it is pleasure, it is misery all in one day. If you work in a ward, some are discharged and others die. Some days we feel like there is no goo din humanity, other days we feel optimistic. However, whether a patient dies on you or succeeds and lives, is your responsibility. And a doctor has to accept the inability to know and fix everything. its a big stimulating world of new words and ideas that help people live healthier better lives. My main interest for medicine came from a psychiatrists office, and we would talk on how we know so little and yet we can do so much. Its only been 60 years since Chlorozapine hit the market. And yet, psychiatry (arguable my favorite and least scientific specialty) has been able to do so much and developed so rapidly in the last half-century that ill people can now live normal lives and feel and love. This ability to make a person's life better: whether to fix his legs or to smoothen his road to death, it may dehumanize your from the world, but ultimately make you richer on the inside. I'd rather be an unhappy, overworked, underpaid internist who commits suicide at 50 rather than a well paid, happy lawyer or businessman.
you work in a climate controlled hospital. my first day on the job, i about blacked out from the heat. i don't need to time travel 4 years down the road to tell you how good you've got it.
