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.
