How to be Smarter: The less often people ask for help from you, the more you should pay attention when they actually do. How to be Prettier: The happiest people I know, dress happy. And dressing joyfully, for most people, doesn't mean black. I don't believe that people wear black because they like it--I believe they wear black because they think it makes them look slimmer, or because they believe they will blend in better, or because they are under the impression wearing colors other than black is more work. I don't think any of those are always true. Dress happy--wear color.
