(Portfolio) This book examines how people allot the 168 hours of each week and suggests that with a little reorganization and reprioritizing, we can dedicate more time to the things we want to do without having to make sacrifices. The author argues that many of us spend massive amounts of time on things that do not help our careers, our families, or our personal lives: for instance, most full-time workers waste about 10 office hours a week surfing the Web or making personal calls. After conducting dozens of interviews, she found that successful, happy people allocate their time differently, making sure that they can fit in the essentials. Vanderkam is the author of Grindhopping: Build a Rewarding Career Without Paying Your Dues and of the nine-part series “Core Competency Moms,” which ran in The Huffington Post from May through July 2008.
