The greatest moment of my sports-loving life came in the early hours of Thursday, Nov. 3, when my Chicago Cubs won the World Series. No matter how long I live, no matter whats to come, theres nothing that could top witnessing a Game 7, extra-innings win 108 years in the making. Even if this championship marks the start of a Cubs dynasty that takes title after title in the coming years, no future win could be nearly as sweet or as cathartic as this one.This is it.

I can feel nothing but warm, fingertips-to-toes gratefulness for the opportunity to experience the kind of ecstasy thats only possible when patience has been tested. The shared happiness understood only by a community long invested in a common goal. The joyful relief of a dream realized.The bond that ties all Cubs fans together remains, but the distinction between those who only dreamed of this moment and those who are living it is stark. Theres no room for melancholy atop this mountain. Too many climbed before us and never reached the summit; it would
