Every hockey team wants a great goalie. But the truth is if the rest of the team is good enough you don’t even need a goalie. Keep the puck at the other end of the ice and the goalie spends the whole game standing there bored. He’s a last resort when your game plan fails.
When you’re trying to change a habit, willpower is your goalie. You want to be able to block all the temptations coming your way, but face enough shots and some are bound to get through. The problem with dieting — well … one of the problems — is that you can spend tons of effort resisting, then one moment of weakness and it’s like you haven’t even tried.
