You're meant to meet someone, or endure a situation, for the purpose of learning. The end result depends on how you interpret these people and events, and the choices you make from your interpretation.
You can choose to live your life with the joy of the front row or solemness of the third row. The choice is yours. That's me in the front row with my joy. Those are my coworkers in the third row. Every day is a struggle to keep them from killing my joy.
