In loving, living memory, John Melançon 1928 – 2007
Finally, a Seth Godin post to which I have something to add.
"Spirit of the Game" contrasts trying to beat the system (maybe it'll work once, and then the rules will be changed) to working the system (chance of repeated success and everyone raising their game and benefitting).
The system he mentions working within include the Internet (really, World Wide Web in this context) and Ultimate Frisbee.
What I would add is that systems not as fair and flexible as the web and frisbee need to be replaced or changed.
Whether or not we want to work the unjust judicial system or the unfair economic field, we must try to change the games to ones worth playing.
So in the sense of working hard to build something in natural systems rather than seeking a shortcut to the top, absolutely I agree. But when it comes to artificial systems that are holding society down, it's less about how you play the game than changing it.
