Presume you do buy into this “fail hard and fast” mantra. If you act recklessly and flail, you will bump your head and it will hurt, and you will do it again, unless you choose to stop flailing and think about why you bumped your head. Of course, no one would ever argue against reflection, but it’s hard to be mindful of the necessity to reflect if you’re constantly being told to move fast and hack or you’ll fall behind. Nevermind the damage those flailing arms do to those close to you…
…You’re also told that you should fail harder, because failure is the gateway to success. Oddly, only successful people say failure is necessary, because anyone who has truly failed in a meaningful, unrecoverable way would advise you to stay away from that shit at all costs. Believe me, I know.
