This link may also help --- it comes from a counselor newsletter that I receive from the University of California system:

Excerpt:
The open-ended prompt asks students to share "anything" they would like UC to know. "Anything" does not mean "everything," Gullatt says. Some students are tempted to write about what they're interested in, though it may not advance their case that they should be admitted.
"Anything," she says, "means one really strategically chosen topic."
A strategic answer highlights or explains what's in the application itself.
One example: A young mother's community college grades were lower one year because her husband was unemployed and she had to work full-time to support her family. The next year, with her husband employed again, she could work fewer hours and study more, and her grades rose dramatically. The bare facts are there in her transcript. But the personal statement gives significance to the transcript, telling the story of a young woman with a high level of self-discipline and sense of responsibility: obviously desirable qualities in a UC student.
