Successful givers secure their oxygen masks before coming to the assistance of others. Although their motives may be less purely altruistic, their actions prove more altruistic, because they give more.

In the workplace, many people become helicopter managers, hovering over their employees in a well-intentioned but ill-fated attempt to provide support. These are givers gone awry - people so desperate to help others that they develop a white knight complex and end up causing harm instead.
