Let night bring to an end every single event of the day which you were disappointed with.
But let night be the right time to celebrate good moments of the day. For every moment of celebration uplifts the spirit to a level where every bad moment is swallowed up.
Before you retire to bed, take the time to assess yourself to know: did you succeed at dropping one bad attitude that has been pegging you to one spot over the years? Or did you fail one more time. If you succeeded fine but if you failed, be consoled by the fact that night will not last forever. It will open the door to one more day, one more opportunity to turn to several blank pages and begin a better chapter of the bestseller of your life.
