When life’s struggles knock you into a pit so deep you can’t see anything but darkness, don’t waste valuable energy trying to dig your way out. Because if you hastily dig in the dark, you’re likely to head in the wrong direction and only dig the pit deeper.
Instead, use what energy you have to reach out and pull something good in with you. For goodness is bright; its radiance will show you which way is up, and illuminate the correct path that will take you there. Read Learned Optimism.
