yah you have no idea what investment banking is...
the bottom line, kid, is that to be an I-banker  you basically have to trade in your idea of a life for what the first guy said: 10-12 hour days with stress coming out your ass, etc. apparently it doesnt get any better for like 5-10 years either. so yeah, if youre REALLY into economics, like meaning you have a huge boner for and cant get enough, then i-banking is right for you. if not, save yourself and do something that's actually going to make you happy, because i-banking is going to take yeeeeears off your life if you end up hating it.
i considered becoming an investment banker at one but, but i completely threw that idea out the window once i realized what a soul-sucking, hellish job it can be. i know a lot of people who are getting offers from huge firms in london, new york, etc, and i actually feel sorry for them...
go to fucking law school and then get into real-estate developement with some of your friends or something, it'll be 100 times better
