The gift of time is often more valuable to the receiver and more satisfying for the giver than the gift of money. We don’t all have the same amount of money, but we all do have time on our hands, and can give some of this time to help others—whether that means we devote our lifetimes to service, or just give a few hours each day or a few days a year.

“Selfless giving, in the absence of self-preservation instincts, easily becomes overwhelming,” says Adam Grant, author of Give & Take . It is important to be “otherish,” which he defines as being willing to give more than you receive, but still keeping your own interests in sight.

We have all felt the dread that comes from being cajoled into giving, such as when friends ask us to donate to their fundraisers. In these cases, we are more likely to give to avoid humiliation rather than out of generosity and concern. This type of giving doesn’t lead to a warm glow feeling; more likely it will lead to resentment. Instead we should set aside time, think about our options, and find the best charity for our values.

I don’t want to discourage people from giving to good causes just because that doesn’t always cheer us up. If we gave only to get something back each time we gave, what a dreadful, opportunistic world this would be! Yet if we are feeling guilt-tripped into giving, chances are we will not be very committed over time to the cause.
