The most elementary of lessons taught early in life is that sharing is important. Some grasp this concept fairly easily while others struggle with it their entire lives.
In a business sense, people who hoard information in an effort to empower themselves are destined for failure simply because they don’t see the big picture: sharing information helps the people around you find success. When other people in your organization are successful, your odds of becoming successful are dramatically higher.
Information is not a form of currency to be hidden, accumulated, and used only to further selfish gains. Rather, recall that sharing strengthens everyone and dramatically improves the rate of success.
