De-emphasize Age, Refocus on Play

Many people probably stop play-like activities because they consider it to be wasted time, much like sleep, and so it gets the axe when time is scarce. Perhaps if they realized its importance, they'd make time for it.
I'm really glad Silicon Valley shops tend to have a playful culture. It makes it easier to fight for it where I work.
I don't mean the idea that you should take your career seriously. That would be lower-case-C careerism. What I mean is the idea that you should evaluate every aspect of your life from a point of view of "will this get me a promotion" or "will this get me a better job?"
That not only causes you to stop playing, but in my experience it kills all creativity dead.
I guess that's where they play side of it ties in... heavy involvement, and the happy-chemicals that go with fun/play help to more easily form mental pathways. Disliking what you're doing, being completely bored/mechanical or having excessive levels of anxiety tends to shut one down mentally.
Work hard and play hard
