Paul Graham has written an article Why to not not start a startup: it is interesting to see his reasons all speaking for doing startups - though they unfortunately (luckily?) do not fit me - but I found also very interesting his view on work paradigm shifts: in the farming society it was strange to leave and go into a city to live with strangers, now we find it hard to believe that the serfs on the farms stayed in that place for their lives ... maybe we will find it similarly strange in the not too distant future to stay in a 'corporate' job instead of pursuing our own projects - like the founders of startups.
