When should you not attempt Hack Reactor(Galvanize)?

When I did this I had never even drank alcohol before and was clean. I had a very rigorous workout schedule so I could do work while working out but do the exact same routine every day. I had no friends whatsoever at the time. But the way it happens is a result of what I mentioned below in another comment about diversity. The programs aren't just selecting for people who have the raw skills, but who have the life circumstances to do this. Perhaps enough savings in the bank from past work. Perhaps a full time nanny for the kids. Perhaps a nurse for the elderly parents. And a family and friends that are expecting to not interact much for a few months. You'll find a lot of the people who do this were relatively successful at their previous career for example, and either don't have a family or have tremendous support from a spouse who is sacrificing their own career and lifestyle to make it work.
