My base salary in my current company is already $150k + bonus, and I like my current job a lot. Meanwhile, my family are strongly against my choice to Harvard since I have a family and am really old, compared to most people here.
In short, the opportunity cost for me to Harvard is really high (half million loss in 2 years). All I want is just to prove myself once in my life, and that's it. Maybe the more important thing in your career is your creativity and related management experience from the real world.
I really don't know if I should go or not. But I'm thinking about the offer seriously,at least 50% chance I'll go to Harvard to chase my dream. BTW, I got my phd from Boston, it is a really nice place for students except the long & cold winter...
