I recently noticed some heartfelt advice from an atheist on a message board that I sometimes watch.
“Life is a one-time roller coaster ride,” he said. “Revel in it. Feel the warm sun on your skin and the cool wind in your hair. Feel the climb up, and take in the rides to the bottom. Don’t spend the entire experience preparing and fretting for what others in the line told you about the exit and what they think comes after, otherwise you will miss the entire experience.”
