This may seem simplistic, but I found that stacking 7.5 face cords of wood leaves you too tired to hold on to petty resentment, and gives you a lot of time to meditate. It also gives you sore muscles and a strong sense of accomplishment that you can see.
The wood stove is in, the house is warmer than I ever felt it when using the oil furnace, and it's full of good smells and toasty heat. Even the far reaches of the house are warm with judicious use of some floor fans to circulate air.
It's hard to worry about petty things when you're tired, warm, and well-fed.
