Learning to love “the things we already have” is always the fount and foundation of contentment, happiness, and wonder:
The whole object of real art, of real romance—and, above all, of real religion—is to prevent people from losing the humility and gratitude which are thankful for daylight and daily bread; to prevent them from regarding daily life as dull or domestic life as narrow; to teach them to feel in the sunlight the song of Apollo and in the bread the epic of the plough. What is now needed most is intensive imagination. I mean the power to turn our imaginations inwards, on the things we already have, and to make those things live. It is not merely seeking new experiences, which rapidly become old experiences. It is really learning how to experience our experiences. It is learning how to enjoy our enjoyments.
