The best advice often comes in short form

Tricked again. I feel like such a sucker.

I was surfing through the library's online card catalog when I came across an irresistible title: "The 15-Minute Home and Family Organizer."

That sounded like something I could surely use. I put in a request through the interlibrary loan system, and within the week, the book arrived.

I could actually feel my pupils dilating when the librarian plunked it down on the counter: It was 3 inches thick. "I can't keep my home and family organized on a day-to-day basis, but I'm expected to find time to read 517 pages of advice?" I gasped.

And then I found myself recalling the words of my son's second-grade teacher, Lynn Walker -- words I've reached for almost daily since she first uttered them during a conference last December.

Knowing that it was our first school year with me working outside of the house full time, she said consolingly, "When I first went back to work after having kids, I would come home at the end of every day and cry."

Paradoxically negative as they may sound, I've found those words inexplicably comforting. Although she refers to herself as "The Mistake Queen" because of her propensity for sending home Thursday's assignment on Friday or mistakenly writing that the field trip is to the Museum of Fine Arts when really it's to the Museum of Science, I can't think of anyone who appears more pulled together in all the ways that really matter. Lynn is calm with students and candid with parents; she emanates good cheer; and after 25 years of classroom teaching at the grade-school level, she appears to love children more indiscriminately than any adult I have ever met.

And yet her first year back at work, she says, she came home and cried every day.

Admittedly, it's disloyal of me to suggest that 20 well-chosen words can take the place of a 500-page book. I'm a journalist by profession, not a speechwriter; I write articles, not sound bites. My livelihood depends on people believing they can find useful information in lengthy pieces of prose.

But it happens to me time and again that a single sentence by the right speaker gives me insight that no published tome can.

I've read dozens of books on parenting in the past eight years, from the creative 1970s "Magical Years" outlook of Selma Fraiberg to the authoritarian 1990s approach of John Rosemond. And yet the advice that has helped me most in the past few years is this: "Talk to your children as if there's no possibility that they'll do anything other than what they are told."

With those simple words, I learned not to make requests of my children -- "Ready to head up to bed? Did you put your seat belt on?" -- but statements declaring what needs to be done. Simple words for a simple concept -- which has replaced volumes of parenting books for me.

Same with marriage advice. "Contempt is the worst possible emotion to engender in a relationship," said a friend of mine. I didn't think it was relevant -- until I realized that contempt was how I felt about my husband's method for loading the dishwasher, and his wish to buy a powerboat. Changing course, I tried to understand his perspective on the dishwasher and his feelings about a boat.

I still disagree with him on both counts, but now I see it as merely a difference of opinion, absent the corrosive edge of contempt.

So "Men Are from Mars, Women Are from Venus" can collect dust, as long as I can remember that short sentence.

These days, when I get home from work and look around my house, I remember Lynn Walker's maxim.

If I'm having a bad day -- the house is messy, important paperwork is missing, the kids are quarreling -- I remind myself that at least I'm not crying, so I'm not as bad off as Lynn once was.

If it happens to be one of the days that I am crying, I assure myself I'm in good company; Lynn used to do the same thing.

And if it's turning out to be a pretty good day and I'm neither crying nor on the brink of tears, but coping, for once, with something like equanimity, well then, I have only Lynn to thank, along with those few words that she probably didn't give a second thought to, in the midst of last December's parent-teacher conference.
