From It's All In Your Head: Thinking Your Way To Happiness by Stephen M. Pollan and Mark Levine (read this book – I mean it):
Life is short, so if you can afford to indulge a bit now and again, go for it. What matters is you realize these indulgences won’t bring happiness.
Instead of looking for happiness, you need to start listening for it. Close your eyes and open your ears. The simple truth is, nothing external will make you happy. Nothing you can see will bring fulfillment to your life. You can lose all the weight you want, find a wonderful life partner, get a fabulous job that pays you an incredible salary, buy a magnificent home and furnish it with everything you’ve dreamed, and you'll still be unhappy. You can get pleasure from external factors, but happiness is an inside job.
It has nothing to do with the physical facts of your life and everything to do with your attitude toward life.
