I feel like it has less to do with moving somewhere and more todo with moving specifically to Silicon Valley. I'd much rather move somewhere like Austin or Denver and save $10k in living costs for my business than spend it on rent in the Valley for one summer.

I agree that there's value in being face to face for mentoring like this, but I just don't see why it has to be in the most expensive place to live in the U.S., especially considering the fact that you want to be saving money when starting a business.
