MarkHsu \$m[1]:I'd say it depends:
--If you are an international student (as in undergrad overseas) and you've done start-up only professionally, it's difficult for schools to "benchmark" the quality of your experience.
--If you are looking to work in a professional/corporate setting post-MBA, having just start-up experience won't help you and could work against you.
I am actually not planning to go back to school any time soon. However, this would be an option for me as long as I see merits in attending B school. My vision is to start a company to make the same impacts that google are making to our society. It would be difficult to achieve this feat with the resources and networking available to me right now. The idea of attending a B school is to learn new things, gather more resources (funding?) and networking (the right people to connect to), and then I can launch my own startup. I thought by attending one of the M7 schools like Harvard might make my vision to become reality. I would want to go back to Taiwan to contribute if I can, because I want to make things happen there. It's still a long way to go, but I have already chose this path so there are no regrets.
thank you very much
best,
James
