If you see some blades of grass unexpectedly emerging from among the train tracks, or if your potted lavender plant has just bloomed, give yourself a moment to take it in, and notice how it makes you feel. Observing nature — wherever you may be — will make you feel happier, researchers say. "To see a World in a Grain of Sand/ And a Heaven in a Wild Flower" – these lines from the 18th-century English poet William Blake are widely quoted, as they remind us that the smallest of things in nature can hold infinite beauty and grace. Or take another poem, by famous Romantic poet William Wordsworth, where he makes a similar point in describing the joy that a field of daffodils quivering in the breeze makes him feel: "my heart with pleasure fills,/ And dances with the daffodils," he writes. According to a recent study, poets like Blake and Wordsworth were definitely on to something. Lead researcher Holli-Anne Passmore, a Ph.D. student in psychology at the University of British Columbia's (UBC) Okanagan Campus in Kelowna, Canada, found that taking just a few moments each day to notice how things in nature make you feel will render you happier and improve your overall well-being. The study's results were recently published in the Journal of Positive Psychology.
