Life is ultimately a single-player game, but the only thing that truly makes it worth living has something to do with our relationships to other people, and this paradox sits at the core what it means to be a human being. Life is problem-solving — and it’s full of problems nobody else can solve for us because they are internal problems that require a change in perception. Others can help, guide, and encourage us, but at its core, the game is still only ours to play.
