This week New York magazine offers some very random happiness tips from a cross-section of New Yorkers — everyone from a personal trainer to an interior decorator to a physician specializing in biorhythms. It’s interesting to see how many different lenses there are on what makes us feel good. The advice runs the gamut from pedestrian (“Exercise more!” — Yawn…) to altruistic (help people with strollers up subway stairs) to just plain odd (eat Greek yogurt). My favorite is the advice to paint your walls yellow. Mine happen to be a pale buttery shade — something I never would have picked, but can’t bring myself to repaint because it’s just so bright and cheery.
