Richelle E. Goodrich said this quote

The secret to happiness is elusive because it is a paradoxical truth. To gain happiness, you must first cease pursuing it. Things perceived to provide happiness are like shiny, pretty bubbles that lure us this way and that way, chasing after their glossy buoyancy. But once they are handled, they “pop”—empty—vanishing along with the hope that happiness could ever be captured. Happiness cannot be caught or won or purchased or even handled. Happiness simply forms like a rainbow in the kindest and most grateful hearts.
