BBC recently cited a study that found the more friends you have, the more you earn. After observing 10,000 U.S. students over a period of 35 years, the study showed that the wealthiest people were those that had the most friends at school. Each extra school friend added 2% to the salary.

The take away: The more people you talk to (i.e. network with), the more chances you have to sell yourself as a likable person. The more likable you are in the eyes of others, the higher chance you have of being retained for professional help. That goes for “in school” and in life.

So don’t be an introvert. Talk to people. Take an interest. It takes a village.
