I got a new one today! Went for a long run (10 miles, outrageously long for me) in the woods. It's been raining heavily, and I passed some beautiful small streams with water that lovely amber colour. Made me smile every time, and then I thought "hey, something that makes me smile = energy". So I ran looking for things I like especially, briar roses, daisies, streams, a friendly passing dog Every one was a tiny boost.
