In those instances in which you find yourself hoping that something will work without being able to convincingly explain to yourself how it will work – that’s when a little bell should go off. Then you should ask yourself clarifying questions. What’s the problem I need to solve? Does this solution actually makes sense (rationally)? If I’m feeling some doubt, why? Am I doing this for sound reasons or am I motivated by something personal?
