Wharton business professor Adam Grant divides the world into three types of people: givers, takers, and matchers.
Most of us, he says, are matchers, meaning we try to keep an even balance of giving and taking. In business, and in life, however, being transactional when it comes to giving and taking is a mistake.
During a conversation with Inc. president and editor-in-chief Eric Schurenberg, Grant explained why giving with no strings attached is more likely to lead to successful outcomes.
"Matchers make the mistake of only helping people that they think can reciprocate...but we can't always predict who's going to go on to do great things and who's going to be in a position to help us," he says. "Givers, by extending their contributions more widely, end up with a more diverse network, so they end up with more connections but also more trusted relationships."
