Barack Obama, Bernie Sanders, Hillary Clinton, George W. Bush, Sir Richard Branson, Steve Jobs, and Mark Zuckerberg have all said that that change or growth happen from the bottom up.

The Bottom-Up Revolution: Mastering the Emerging World of Connectivity, picks up where Malcolm Gladwell's Tipping Point left off. It is a how-to book for businesses, leaders, organizations, activists, and individuals, cracking wide-open humankind's biggest trend in seven million years. By understanding the roots and implications of "bottom up" and "top down" you'll be better able to tap the incredible power of this trend, as the billionaire founders of Google, Facebook, Craigslist and Twitter have done.
