A persistent quest against a fear or toward a goal is often the best course of action. Repeating the same constructive behavior over and over, hoping (one day) for a positive result is difficult but virtuous. It's the effort made by eating oatmeal every morning, brushing your teeth after every meal and daily journaling. It's weekly therapy, consistent workouts and taking time for spirituality. It's Rudy trying over and over to get into Notre Dame. Or Mother Theresa tirelessly serving the poor. Or someone working to systematically overcome shyness, build healthier habits or communicate better with their spouse. It's a 12-stepper taking it "one day at a time." The qualities of perseverance, consistency, loyalty - these are beneficial to health and definitely not insane. And they're doing the same thing every day, hoping for some measure of progress. - https://www.psychologytoday.com/us/blog/in-therapy/200907/the-definition-insanity
