" First, you can develop resilience. Anyone can do it. No one can do it for you. You and you alone have to do the work. Second, you can develop resilience. It’s possible to build virtues. It’s possible to change your character. It’s possible, therefore, to change the direction of your life. Third, you can develop resilience. Resilience cannot be purchased or given to you; you have to do the hard work of building excellence in your life. "
