When I read something powerful -- a quote, a story, a reflection -- I write it down or cut it out or make a copy of it and drop it into a file folder I've titled inspiration. This file, among others, has been on many a moving van and has traveled with me all over the East coast, from city to city, house to house. And every once in a while, when I need a lift, this is my go-to file -- I go to it, pluck something out, and refresh my mind and spirit.

This file has been with me since at least 1997 -- the date on a photo-copied Ann Landers column I have sitting before me. It's 10 years old, but there's nothing dated about the words printed on this single sheet of paper. They are as touching and moving and relevant now as they were when I first read them. They may be even more meaningful today, because of the thread of cancer that is now woven throughout my days.

These are life lessons, offered by a publisher of the Mount Pleasant News in Iowa, for students about to graduate from high school. They go like this:

Dear Graduates:

There is the kind of education you get in school and the kind you get afterward. Both are important. Put them together, and you have wisdom. The trouble is, life is generally half over before you figure out what is going on.

Graduating seniors can save 25 years of trial, error, and hard knocks by memorizing the lessons of life listed below.

On the average, you learn about one big lesson per year after you leave high school. In really tough years, you learn two or three. Some years, you don't learn anything. After 40, you forget things and have to learn them again.

Some of this information is borrowed. Some is stolen. Some may even be original, but that's doubtful. It's pretty hard to be original in a world as old as this one.

25 Things You'll Need To Know After High School

1. Don't sweat the small stuff, and remember, most stuff is small.
2. The most boring word in any language is "I."
3. Nobody is indispensable, especially you.
4. Life is full of surprises. Just say "never" and you'll see.
5. People are more important than things.
6. Persistence will get you almost anything eventually.
7. Nobody can make you happy. Most folks are as happy as they make up their minds to be.
8. There's so much bad in the best of us and so much good in the worst of us that it doesn't behoove any of us to talk about the rest of us.
9. Live by what you trust, not by what you fear.
10. Character counts. Family matters.
11. Eating out with small children isn't worth it, even if someone else is paying.
12. If you wait to have kids until you can afford them, you probably never will.
13. Baby kittens don't begin to open their eyes for six weeks after birth. Men generally take 26 years.
14. The world would run a lot smoother if more men knew how to dance.
15. Television ruins more minds than drugs.
16. Sometimes there is more to gain in being wrong than right.
17. Life is so much simpler when you tell the truth.
18. People who do the world's real work don't usually wear neckties.
19. A good joke beats a pill for a lot of ailments.
20. There are no substitutes for fresh air, sunshine, and exercise.
21. A smile is the cheapest way to improve your looks, even if your teeth are crooked.
22. May you live life so there is standing room only at your funeral.
23. Mothers always know best, but sometimes fathers know too.
24. Forgive your friends and your enemies. You're all only human.
25. If you don't do anything else in life, love someone and let someone love you.

Nearly a decade ago, women in Long Island began to worry about their high rates of breast cancer. So they advocated and lobbied and pushed until a public law was passed that allowed for the creation of the Long Island Breast Cancer Project. Funded by both the National Cancer Institute and the National Institute of Environmental Health Sciences, great data has emerged from this project -- like the data linking breast cancer and household pesticides.

Although much research has linked cancer with pesticides in work and industrial settings, few studies have investigated what these chemicals can do in households -- until now, thanks to research conducted as part of The Long Island Breast Cancer Project.

Published online in the December 13 American Journal of Epidemiology, researchers found an association between lifetime residential pesticide use and breast cancer risk in a sample of 1,508 Long Island women diagnosed with breast cancer between 1996 and 1997. These women were compared to 1,556 random controls. All women were asked to self-report their pesticide exposure and to offer blood samples for the study of organochlorine compound levels -- found in lawn and garden products.

As expected, researchers found an increased breast cancer risk for women whose blood samples showed the highest levels of organochlorine compounds. They also found it hard to find women who did not use lawn and garden pesticides to some degree.

Use of household pesticides has infiltrated our society, says researcher Susan Teitelbaum, assistant professor in the department of community medicine at Mount Sinai School of Medicine in New York, who reports she is happy to see a movement toward use of alternative methods, like integrated pest management.

Teitelbaum has just one recommendation as result of this study. It's quite simple really -- stop using pesticides.

Four-time Iditarod champion Susan Butcher died Saturday of complications from a recent bone marrow transplant. Her health concerns began three years ago when she was diagnosed with polycythemia vera -- a rare disease that causes bone marrow to produce excess blood. Then last winter, she was diagnosed with leukemia. Her subsequent bone marrow transplant on May 16 cleared her system of cancer. But she developed graft-versus-host disease -- where transplanted cells start attacking the digestive system. A fever, a change in her potassium level, and a trip to intensive care prompted her husband to write on his blog Friday of her condition. He reported that if she remained stable, she would return to her previous hospital room and would work on recovering. But sadly, Butcher did not recover.

Butcher dominated the 1,100-mile sled-dog race from Anchorage to Nome in the late 1980s and brought national attention to the grueling competition. She won the 1986 race and became the second female champion -- and then won again in 1987, 1988, and 1990. She finished in the top four through 1993. Butcher also made headlines in 1979 when she helped drive the first sled-dog team to the 20,320-foot summit of Mount McKinley -- the highest peak in North America.

Butcher, who ran her last Iditarod in 1994, grew up in Cambridge, Massachusetts and was married with two daughters -- ages 10 and five. Butcher was 51 years old.
