‘The Secret’ changed Katherine Heigl’s life. Well, rather, the script for the movie based on ‘The Secret’ that Heigl didn’t actually end up starring in changed her life. “I had always kind of pooh-poohed it,” she said. “And then I read the script about 6 or 7 years ago, and there was something about it that resonated with me. This idea that we sort of bring about what we think most about.” Reading ‘The Secret’ led to reading books on manifestation, intention work, mysticism, crystals and witchcraft. “It’s gone in many different directions,” said Heigl, who was raised in the Mormon faith. “But what it’s mostly helped me discover is, I’m in control. I just feel happier than I did at 35, at 25.”
