to me, it feels overly optimistic in 2 ways.

1. it makes the assumption that failure is always positive

self improvement dogma: "fail faster, you learn from each failure"

peter thiel: "each failure is a tragedy, it is multivariate and therefore often too complex to truly learn from"

2. dunning kruger syndrome and learning something "the wrong way" is possible in more than one field.

Overall it was a nice read though
