“Attention is like energy in that without it no work can be
done, and in doing work is dissipated. We create ourselves by how we use this
energy. Memories, thoughts and feelings are all shaped by how use it. And it is
an energy under control, to do with as we please; hence attention is our most
important tool in the task of improving the quality of experience.”
—Mihaly Csikszentmihalyi, Flow: The Psychology of
Optimal Experience
