How to be Smarter: I highly recommend this book to everyone--knowing about the economy--and terms that are used to describe it--is so important for being a productive citizen. This book is long, but is broken into easy to read short sections--throw it in your bag and read a section or two on the subway each day. How to be Prettier: Winter coats are on sale now despite there still being two or three more months of cold weather--give yourself a mid-winter boost and pick up a new one on sale today.
How to be (less) Awkward: When you must cancel plans, tell the other party as soon as possible. And don't commit to things that you think you may have to back out of.
