"Take annoyances in stride."
~ Richard E. Turner
I can be feeling confidant and on top of the world and one small thing- an interaction with an unfriendly other, a disappointing meal, the dog being needy- can trigger me into a funk. It's like a cloud that covers the sun. I am temporarily shadowed. And I suppose I can't stop the effect of the triggers, but what I can do is allow them to pass.
When I feel myself suddenly disgruntled, I let it be and don't resist it. I breathe and trust and let time move me forward.
