We're probably thinking of very different things. By learning I meant learning every aspect of launching a startup, including customer development, sales, marketing, SEO, etc. If your role in the startup was limited to programming, then I'd take a very jaundiced view of the state of affairs. And by no means would sacrificing relationships and health compensate for even this.
