*get educated in a country where the medschool is free or half the cost (do research)
*then take the exams here and pass
*it's great if you do not plan to get married or have kids, if you're female, otherwise, more money will be spent on freezing eggs
*consider the work life balance and the trade-off
*consider the cost of paying for med-school if you don't have the free-ride option, and its effects on investments later on, like a car or house, or travel
*consider the cost when you decide to not practice in the end to raise a family instead
*know that if you marry someone that will eventually go to med school that will not pay for their med school, that the responsibility may be transferred to you
*if short lifespan runs in your family, consider what other jobs may be finished much faster. there are other jobs that help people.
*if it's about money, there are other jobs that make a lot of money in a short amount of time
in short, I recommend that people who can afford to go to med school without a loan, with excellent physical health should go. and those on the opposite spectrum shouldn't unless they get into a better situation. i'm not saying it isn't doable, but to just know these details upfront before being immersed halfway through med school. and i'm sure there are some people who just go to med school because they like taking tests.
