Jong has made a career and a ton of money with nothing but personal spewing. She even married a psychiatrist (Dr. Jong) in hopes that he'd be eternally fascinated with her personal spewing. He was not.
However, Fear of Flying, her first book, was great fun to read, as she's a clever writer. After that, however, her spewing was repetitive.
The only thing I remember about that book is that she peed in her shoe. To this day, I wonder why she didn't drive to a rest stop.
