Out of college, I worked for 80-100 hrs/week, 7 days a week, including holidays (4th of July, Thanksgiving, etc). Got to take one week off each summer. Did it for three years, quit my job and spent a full year traveling.
Admittedly, being a bitch in some industries is more lucrative than others but at the end of the day, depends on what you really want to do. You could hate your job in a year or two, you never know.
