Another technique I use...
When there are things out there I can't control, like in politics or on the news, I focus on some aspect of self sufficiency. Something I can control that THEY (whoever THEY are at the moment) can't take away from me.
I sat in the gallery and watched my state legislature take away my union (I'm president of my union local). I had lobbied and talked and walked and had done everything I could, but was just ignored. They smiled and listened and thanked me participating in my government, then just went in there and took it away.
All the local media wanted a reaction. I kept a stiff upper lip and said what I had to say for the good of the people I represent.
Then I went home, left the TV off, and worked with my goats, chickens and garden. Started a new irrigation system with my pond. Worked all of that hurt and frustration out of me.
There is comfort in that.
