this thread's pretty old, but ill throw in my two cents here.
my dad was an investment banker for a few years. the main reason he got into investment banking was the same reason he got out of IB, the exit opportunities. Investment banking is probably one of the most respected jobs in the finance world. if you do well in IB, you can do well in almost anything in the finance world.
my dad was well out of the analyst position by the time i was born. my mom told me and my 4 sisters that there would be times where she would go days without seeing him. that is the kind of schedule you can expect. he says that it could have been worse because usually he could go in the office early sunday and be out of there by 1 o'clock. you dont get paid to put family and fun first. if you want to make the money, you had better be willing to pay the price.
you should never do something for the money. IB looks great to a lot of people because of the money. sure you could make a lot right out of school and the money only increases, but most people are turned off once they find out about the hours and the actual work.
today, my dad is a Venture Capitalist. he still works 60 hours a week (sometimes less and sometimes more depending on the time). he likes it a lot more than investment banking.
but cool thread, happy i came across it.
