This.

I read here on HN some time ago an article stating that teenager-ish people crave to find "meaning" in work due to being what in essence can be described as emotionally retarded (although intellectually normal). This all changes fast as they age and/or have kids or other inevitable live event that manages to pull their head out of their ass.

Basically Mark Twain's "When I was 17, my father was so stoopid" remark.
