Ultimately you know what motivates you. If you are passionate about what you are studying in school then I'd say stay, no amount of salary can replace job satisfaction and money doesn't necessarily make a job any more bearable. I posted up about the situation I am in, good job making a very generous salary but the job I love pays half (almost a 3rd) and I am busting my ass to get there.

I will say this, one event sent me down the path that I am on now. I was 19 making $60k+ which made for a very nice lifestyle at the moment but looking back had I pursued what I was really passionate about I would be much happier and farther along than in a stagnant career field. When you make a good salary your lifestyle will reflect that making it harder to transition should you decide to pursue something else in the long run.

I guess I said all that to say.. do what you are passionate about. If you are passionate about money (nothing wrong with that) take the job. If you choose the job I cannot stress enough to invest and put yourself in a position where you have options.
