Life, my dear Watson, is infinitely stranger than fiction; stranger than anything which the mind of man could invent. We could not conceive the things that are merely commonplace to existence. If we could hover over this great city, remove the roofs, and peep in at the things going on, it would make all fiction, with its conventionalities and foreseen conclusions flat, stale and unprofitable.
I've seen optimism because I grew up in communities of recovery where people put their lives back together and find tomorrows that they didn't think would be there. That fundamentally changed my life and is so much of where my hope comes from.
