The red Lamborghini did little to improve Paula Poundstone's mood.
She says she was "feeling like a jerk" as she drove it through Los Angeles, a self-inflicted experiment to discover the secret to happiness.
"We live in a world where there's a lot of people who don't have homes," she says. "And who wants to drive by that in a Lamborghini? You know, I don't like walking by it to get on the train. So it just it creates a much more stark reminder of the inequities, you know, the imbalance in in our world. And you know normally I just walk down the street feeling helpless to help people."
She also tried camping, taekwondo, volunteering and other activities as she searched for deep personal satisfaction. Some became habits.
