The quote from Rabbi Glassman in Simone Elkeles' book "How to Ruin My Teenage Life" suggests that the value of good days often comes from having faced challenges and difficult times. Experiencing hardship can deepen our appreciation for moments of joy and happiness, as it allows us to understand the contrast between struggle and contentment.

This perspective invites reflection on personal growth through adversity. By navigating through tough experiences, individuals can gain resilience and a greater recognition of life's positive moments. It emphasizes the importance of balance in our emotional experiences and suggests that the lows in life can enhance our gratitude for the highs.
