I used to consider myself pretty busy, weekdays hardly any time for anything else other than work. I was talking to a person, who is planning to move from semiconductor industry to Investment banking. think about this...
An average invest banking associate, say in Goldman Sachs spends at least 80 hours a week in work for atleast first 4 years, until he becomes VP.
thats startling... some motivated, crazy guys even log 90 - 100 hours a week.
May be thats a sacrifice , when you make more than 200k per year.
Now I need to rethink or rephrase... when I say or think I am busy :P :)
