None of us are immune to illness, death, the loss of loved ones, and bad fortune simply by virtue of being sober. Working on our sobriety allows us to manage all these things much better than we could ever imagine. And remembering our better days helps us through the darkness.
Grounded, reliable sobriety reframes life as an adventure to be lived, instead of a problem to be solve. Sadly, and though this is available to everyone, not everyone is up to the challenge.
