Efforts to lose weight can feel like however hard you try to do the right thing, you make little progress. Those who like games can use terms like winning, losing — or cheating? What must you do to win? If this analogy applies to you, ask yourself if you've defined the rules properly. If your criteria are too vague, it can feel like it's going nowhere: so change the rules to make it winnable. Focus on day-to-day choices rather than impossible standards, and progress may become more realistic.
