What is happiness except the simple harmony between a person and the life they live?
Most of us are lucky in that we have more agency in our lives than we may realize. If we do nothing but try to manage well what we do have control over, we’ll find that we have more control than we think. This realization makes it easier to deal with the things we actually can’t control.
Being attentive to what’s going on around us and where we fit in is indeed an element of our basic mindfulness.
