I agree with so many of these. I try to "live in an attitude of gratitude". When I think every thing is bad I try to stop and say...okay..do I have shoes on my feet? That's good..Do have clothes on my back? That's good..Do I have a roof over me? That's good. Do I have my cats that love me no matter what? That's good.
I take it from there and it helps me put my problems in perspective.
