Kate Hudson reveals her new mantra for 2016

It's been 16 years since Kate Hudson landed the career-making role of Penny Lane, the free-spirited rock-n-roll groupie in "Almost Famous."

Twenty years in, the 36-year-old Golden Globe-winning actress and mom of two has Hollywood hits and a marquee name. She is also the co-founder and face of Fabletics, the active wear company that last year brought in more than $150 million in revenue.

Now, Hudson is adding author to her resume, with her new lifestyle book, "Pretty Happy: Healthy Ways to Love Your Body." She describes happiness as a kind of "discipline."

"Especially for women, kind of like throwing these images - these gorgeous images of these women out there... and we chase it and chase it and chase but at the end of the day, it's never going to be perfect," Hudson told "CBS This Morning" Wednesday.

Instead, the actress and her famous mother, actress Goldie Hawn, have adopted a new mantra for the new year: Why not? She said this new attitude in life has allowed her to focus less on the outcome.

"I think I spent a lot of my time in my life being very sort of political and careful about things that I've said or things that I'm doing and worrying about what people are going to think," Hudson said.

The actress will also be making a return to the big screen in the fall for the movie, "Deep Water Horizon," which also stars her stepfather, Kurt Russell.

Her mother will also be making a comeback after nearly 14 years for Amy Schumer's new comedy show.

Hudson also commented on her rumored new beau, singer Nick Jonas, calling him "a great guy."
