Beautifully put @Sister, and well reflected on @iserbrown.
I wrote about this yesterday on another thread. For me positivity is something I can sometimes manage within the framework of realism. BC has caused me to lower my sights considerably. Like you @Sister I can be positive about managing my daily activities, that the dinner I'm making will be tasty, that I can make sure everyone has clean clothes etc. Beyond that I don't feel positive about anything much and that's something I'm working on with my psychologist. I don't feel certain about my ability to cope with any more disaster. But I suppose when it occurs I shall have to go through it, positivity or not. That's realism for me.
My BC experience has reframed my concept of positivity into mindfulness, staying present, reining in expectations, and focussing on enjoying the simple pleasures of the moment. These are concepts, ways of being, with which I am now more comfortable.
Great topic. K xox
