I could be wrong, but I think this letter illustrates why why many of us are attracted to startups. This kind of esprit de corps, this sleeping under your desk and working around the clock doing everything you can to move the ball forward, this single-minded insanity that focuses 100% of your effort and will on building something amazing and changing the world forever. Is it probably just naive and idealistic and ridiculous? Yeah, it probably is. But I think at the end of the day, many of us just want to be that committed to something.
