The thing that changes your professional life, your capabilities, your learning, your understanding, your opportunity flow, your ability to make things happen, is the center relationships you have with powerful and effective people around you in the industry, in the activity that you want to be doing.

People generally worry about social networking more than they need to. In kind of consumer internet investing and on social and professional networks, I kind of look at time spending and time efficiency. You know, time saving sites. So on time spending sites, things where you play lots of games or that sort of thing, you might worry about a productivity loss if people are spending a lot of time doing that. So if there's a lot of kind of addictive gaming going on during work hours, that won't be as helpful to you.

Entrepreneurship is a life idea, not a strictly business one; a global idea, not a strictly American one.

One of the challenges in networking is everybody thinks it's making cold calls to strangers. Actually, it's the people who already have strong trust relationships with you, who know you're dedicated, smart, a team player, who can help you.
