"it'll all work out" is an effective tool to deal with irrational or counterproductive anxiety (irrational== fear of flying, fear of social settings, etc., counterproductive==survival situations, situations with no other reasonable extrication than through, i.e. you need to swim to safety, you're stuck in a cave, you have a huge presentation to do tomorrow). It's entirely a bad idea to use in lieu of rational decisionmaking (i.e. "Ill enter into this horrible business deal, itll all work out!"). If you have generally negligible amounts of anxiety in life, the attitude is probably useless. For those of us that have tons, the judicious usage of this attitude is definitely a lifesaver.
