flow
n.— «Winter’s approach and, with it, our deepening commitment to our work, is a good time to remind ourselves of the theory of “flow.” Coined by Mihaly Csikszentmihalyi,…flow is an optimum state, what we all want when we work: a feeling of utter engagement, rapt concentration and singularity of purpose.» —“With winter coming, think flow, not snow” by Judith Timson Globe and Mail (Toronto, Can.)
