I think this is the key. You have two years of runway to figure out what to do next (according to the blog). That money in the bank is a lot more security than any job can offer, by itself. Staying in your job for another two years might be the greater risk, when opportunity costs are taken into account.
Cool. I hope I didn't come across as being overly negative. I actually think what you're doing is awesome! I was just pointing out that a job isn't the only "trap" you can fall into. I know someone who acquired a million dollars in his mid-20's, but I can't say he's really living his dreams because of it. I don't think you'll have too much of a problem, looking at your track record, but it does appear you have to be careful to ensure that "I can do whatever I want" doesn't turn in to "I don't do much of anything."
