The part about pivoting is interesting. For a musician, changing the genre of the band has to be quite difficult, because an style is likely developed and the soul to the art will have to be changed. I wonder if it's the same for entrepreneurs, who likely have an affinity to a particular field due to passion or expertise. Pivoting, by definition, shouldn't be a complete redo, but I'd imagine it's as hard of a choice for a startup to pivot drastically as it is for a band to change genre.
