From interacting personally with internationally renowned thought leaders and experts like Mahan Khalsa, Chris McChesney and many others I've picked up quite a few lessons worth adopting.
First of all, being a people person, a networker or someone successful in sales is something you learn. You too can become an influential individual, doing much good wherever you are. Science supports this fact.
Secondly, you don't need to reinvent the wheel. Most of the challenges you're faced with have been solved in a principle based manner a long time ago. Listen to the experts and change your behavior to get different and better results.
Third... Sales skills are essential if you want so succeed together with other people.
