single-player game..............

 

Socially, we're told, "Go work out. Go look good."  That's a multi-player competitive game. . . . We're told, "Go make money.  Go buy a big house."  Again, external multi-player competitive game.  Training yourself to be happy is completely internal.  There is no external progress, no external validation.  You're competing against yourself—it is a single-player game.
