" givers and takers differ in their attitudes and actions toward other people. If you’re a taker, you help others strategically, when the benefits to you outweigh the personal costs. If you’re a giver, you might use a different cost-benefit analysis: you help whenever the benefits to others exceed the personal costs. Alternatively, you might not think about the personal costs at all, helping others without expecting anything in return. If you’re a giver at work, you simply strive to be generous in sharing your time, energy, knowledge, skills, ideas, and connections with other people who can benefit from them. "
