Short books usually give you the juicy details in a format you can read over a long lunch. Each of these books is only about a half-inch thick but packs quite a bit of wisdom.

"Please stop waiting for a map. We reward those who draw maps, not those who follow them."

"In this sense, time management is really life management, the management of yourself. The quality of your time management largely determines the quality of your life. What you choose to do, and in what order, and what you choose  not to do determine your levels of happiness and satisfaction more than anything else. You will always feel more balanced when your time is spent on achieving goals that matter to you."       

"I define an engaged leader as someone who uses digital, mobile, and social tools strategically to achieve established goals as they relate to leading people and managing organizations. While Millennials are digital natives and accustomed to sharing all aspects of themselves with their virtual friends, today's top leaders seldom share the same passion for openness."

"Regularly interrupting the day to bring our best minds together to focus on the urgent makes it impossible for these  people to spend their focused energy on what's actually important. We have created a culture designed to survive the  urgent by watering it down, instead of challenging our best to step up and lead us to do the important."

"Never forget that absolutely everything you do is for your customers. Make every decision---- even decisions about whether to expand the business, raise money, or promote someone -- according to what's best for your customers." If you're ever unsure what to prioritize, just ask your customers the open-ended question, "How can I best help you now?" Then focus on satisfying those requests."

"There have always been long-range visionaries in business. Henry Ford, Walt Disney, Bill Gates--people who changed the world through unconventional logic, perhaps not necessarily thinking first about making money. Remember, we don't want to think about profits first, but we do want to be sure someone is thinking about them at some point, when investors and stakeholders expect them. The best of these entrepreneurs, surrounded themselves with reliable, straightforward colleagues, who filled out their skill sets and told them the truth. Hype makes for bad decisions."

"Human beings prefer to organize in tribes, into groups of people who share a leader or a culture or a definition of normal. And the digital revolution  has enabled and amplified these tribes, leaving us with millions of silos, groups of people who respect and admire and support choices that outsiders happily consider weird,but that those of us in the tribe realize are normal (our normal). My argument is that the choice to push all of us toward a universal normal merely to help sell more junk to the masses is both inefficient and wrong."
