Do you prefer to be hands-off, giving money to worthy organizations that are doing good work? Or do you want to be an active donor who takes a board position and works closely with the group’s executives? Both approaches can be effective. Melinda and Bill Gates epitomize the active donor, spending tremendous amounts of time and money through their own foundation to fulfill their vision for improving the world. Warren Buffett, on the other hand, is a good example of a hands-off donor. He saw what the Gates were doing, liked it, and opted to give large sums to the Gates Foundation to use as it wished.
