Last week I talked to a person who quit his job to do some soul-searching. He spent last 8 month traveling, helping a few startups, living in San-Francisco(for a month), and doing some fun part-time work.
His advice was "have a few goals". You can quit your job and have a few fun months, but after that you'll have to return back to your previous life and problems that you had will be likely unresolved.
I am curious: what kind of change happened to your friends' lives? I'd like to take a few months off work, but I am considering a more directed approach than funemployment. Funemployment is certainly great for some people, but probably not for me.
