There are several ways to build a startup or invest in startups. For a founder or investor I think it is a big win to find the way that works for oneself, where one can be authentic, find enjoyment in the day-to-day work and adapt the work to one’s strengths.
That doesn’t mean that all of the rules should always be ignored (they are often rules for a reason), but one should understand them so one knows when to bend (or ignore) one of them.
