36 yo here. I've found that it is incredibly easy to 'overthink' and therefore overengineer things, and I've seen a LOT of my coworkers fall into that trap. Analysis paralysis is real, and delivering something and then being able to iterate on it is a massive step in overcoming that. Way wayyyy too often I've seen people try to think of all the edge cases before starting work, and that's just not a viable approach to software development in today's world.
Also, disclaimer, I didnt actually read the article :o
