Geoff Thompson once noted that, left unattended, dark thoughts will overtake us, but that positive thoughts require constant, deliberate attention. I think that’s true.
As St. Claire said in Shoreline Gold, the road to hell is wide and smooth. It’s an easy route to take. The default. You have to make a choice to be positive. You have to make it a habit.
To quote another great thinker, life is as good as you let it be.
