Last month, I spent a day in a library for the first time in over 20 years. I was there to work, but I appeared to be the only one doing so. Everyone else lolled about as the rain fell outside, helping themselves to the endless shelves of newspapers and magazines or browsing the newest fiction.

My work brings me joy. But as I looked around at the older patrons especially, I was overcome by a single emotion: jealousy. It had been too long since I’d sampled the simple but profound pleasure of losing myself in the stacks. I wanted to feel it again.

That craving stayed with me, and it helped me recognize how important some research from the June issue of The Journal of Consumer Research could be for helping many Americans find peace of mind as they contemplate their retirement savings. The lead article reported that older people often draw as much happiness from ordinary experiences — like a day in the library — as they do from extraordinary ones.

For people who have not saved enough or have broken into their savings because of lost jobs and health crises, the findings offer a glimmer of hope. If you can cover basic expenses, pursuing inexpensive, everyday things that bring comfort and satisfaction can lead to happiness equal to jetting about on international trips in your 70s and 80s.
