Some of the most useful life advice comes from people who have had the longest time to test it. A Cornell research effort asked older Americans, from their 70s to well past 100, what they would pass along, and five lessons rose to the top.
They are not complicated, which is partly the point. Life is short, worrying wastes it, work should be enjoyable, happiness is a choice, and the body deserves long-range thinking.
Lesson 1: Life Is Short
If one theme was unanimous, it was this one. The Harvard Gazette’s 2013 account of the project says the Legacy Project surveyed almost 1,500 people from their 70s to over 100, asking each to name the most important lessons learned over a lifetime. Nearly everyone made the point that life is short.
A retired engineer said life “passes in a nanosecond,” the Gazette reports, and a 99-year-old woman remarked that she turned 100 before she knew it. The speed is a surprise even to the people who spent decades planning around it. Experience has its uses, which may explain why boomer habits are making a comeback, and households led by adults 80 and older are projected to double by 2040, so more voices like these are on the way.
That perspective shows up in how older Americans describe their own memories. A list of everyday experiences boomers remember reads like a catalog of days that felt long and turned out to be short, and the generation behind it is large, with baby boomers making up 37% of the U.S. population at their 1964 peak.
Lesson 2: Worry Less
The second lesson came from a question about regret. According to the Gazette, most respondents did not mention affairs or business dealings. They said they wished they had worried less, because worrying about things that cannot be controlled wastes a lifetime.
NPR’s transcript of Pillemer’s interview adds a human example. Helene Rosenblatt returned to college decades after first starting and found that her doubts were mostly unfounded, and her advice was simple: “Just go for it, go do it,” according to NPR.
Putting things off is the cousin of worrying, and there is a whole shelf of advice on how to stop procrastinating that echoes the same idea. The elders’ version is shorter: stop rehearsing and start. The hardest truths baby boomers say are tough to accept make a similar case.
Lesson 3: Choose Enjoyable Work
Hard economic times did not change what the respondents said about careers. The Gazette reports that they did not urge younger people to chase stable, high-paying jobs, but to choose work for enjoyment and purpose, since life is too short for work that feels like a sentence.
On NPR, one elder advised finding work that is loved without fretting over the compensation, and another said life is too short to spend time on something that does not feel purposeful and meaningful.
That is easier said than done, and the list of common choices in life that are actually really bad includes a few career moves. Even so, the elders’ point stands: the paycheck matters less in hindsight than the hours it required. Older adults pass along advice on manners too, as in five restaurant, movie and family manners AARP’s Ethel says older adults should remember.
Lessons 4 and 5: Be Happy Anyway and Think Long
The fourth lesson is to take responsibility for happiness. Younger people often assume they will be happy “if only” something changes, the Gazette says, while older respondents described contentment that exists despite circumstances. One octogenarian, Helga, who lost her daughter in a plane crash, said she eventually stopped tormenting herself and chose to focus on the living. NPR’s account of June Driscoll, frail in a nursing home but cheerful, makes the same point: she saw being happy as her job.
The fifth lesson is to think of the body as something that has to last. Rather than offering standard health tips, the Gazette says, respondents advised treating the body as if it would be needed for 100 years. It is a reminder about long-range thinking, not a medical prescription.
Pillemer, a Cornell professor of human development and gerontologist, has said his aim was to ask older people “what they know about living that younger people don’t,” according to the Cornell Chronicle. His book 30 Lessons for Living grew out of the project. Figures differ by account: the Chronicle describes the book as drawing on more than 1,200 people age 65 and older, with the oldest interviewee 108, while the Gazette cites almost 1,500.
Why the Lessons Hold Up
Cornell’s Legacy Project page says the effort began in 2004 under Pillemer and has produced advice on being happy day to day, building a fulfilling career and growing old fearlessly and well. A 2012 Cornell piece describes the older Americans as “the experts,” drawing on what they say they did well and what they would change.
Pillemer also noted that surveys show older people tend to be happier than younger adults, and he called the failure to draw on older generations’ wisdom a major missed opportunity, the Gazette says.
The five lessons fit on an index card, which may be why they last: life is short, worry less, enjoy the work, choose happiness, and plan for a long road.
