It takes more than hard-nosed risk taking to make it as an entrepreneur. You also have to be charismatic and a great listener, writes blogger and venture capitalist Mark Suster (see bothsidesofthetable.com):

"Being tenacious without the mental flexibility to pivot based on market feedback is a disaster. Having street smarts with no inspirational ability to build teams can yield a great small business but will be difficult to scale into a large VC-backed business. So we as VCs search for entrepreneurs/founders who have the whole package or as much of it as possible. Few people have it."
