He had a generous spirit, which anyone can afford. For example, he was a very busy man, but he was generous with his time. Sometimes it took a couple of months to get on his calendar, but if you truly needed him, that phone call would come right away. Most of the time, these little gifts were what Adam Grant, crediting businessman Adam Rifkin in his book Give and Take, calls five-minute favors. They are easy for the person doing the favor, requiring minimal personal cost, but mean a lot to the recipient.7 Grant also notes, in a 2017 article written with Reb Rebele, that being an effective giver isnt about dropping everything every time for every person. Its about making sure that the benefits of helping others outweigh the costs to you. People who do this well are self-protective givers. They are generous, but they know their limits. Instead of saying yes to every request for help, they look for high-impact, low-cost ways of giving so that they can sustain their generosityand enjoy it along the way.
