How Betty White Reminds Us Of The Importance Of Finding Our Purpose & Passions

Betty White is celebrating another year of life, but if you ask her about her age, she's quick to remind you of one important fact: It doesn't really matter. The sitcom star turns 99 on Sunday, and she's still got an active career.

"You don't fall off the planet once you pass a given age," she said in a 1991 interview. "You don't lose any of your zest for life, or your lust for life, if you will."

Now 30 years later, and in the face of continued sidelining of older women in film and television, White has continued to have a successful career—and it's part of her secret to longevity, even if she says she doesn't have one.

"I don't have a secret," she said in a 2018 interview with Parade. In the same breath, however, she said she plans to "never" retire. In another interview with the publication, she said, "I just love to work, so I'll keep working until they stop asking."

Her love of her work, and the sense of purpose it gave her, is probably a major part of White's years of active success. Having purpose has been linked to improved physical and mental well-being, and it's also been shown to help protect your brain.

White acknowledges that keeping busy has been a crucial part of her long and productive life. She encourages others to find their passions and to run with them.

"It's not hard to find things you're interested in," White told Katie Couric in an interview to mark her 95th birthday. "Enjoy them. Indulge them. And I think that keeps you on your toes."

In her interview with Couric, she also reminded people to take a broader view of their world and their life: "Don't focus everything on you; that wears out pretty fast." She's also all about self-reflection: "You can lie to others—not that I would—but you cannot lie to yourself," she told People ahead of her latest birthday.

In the same interview, the actress also shared that she always tries to focus on "looking at the positive side," on the happy moments and joyful things.

White is actively involved in supporting lots of causes, many tied to things she loves, like animals. She's a trustee of the Greater Los Angeles Zoo Association and wrote a book called Betty & Friends: My Life at the Zoo. She's also said she aspired to be a forest ranger or a zookeeper before she decided to pursue acting. In fact, she's actually been made an honorary forest ranger.

The other thing she focuses on? Living in the present and enjoying what life has given her. "I don't think about things I might have missed out on," she told Parade.

In her Couric interview, she also gave advice for dealing with grief after loss, saying she focused on what was happening in the moment. "You don't look ahead, and you try not to look back," she told the host.

Although it's difficult to be fully in the moment, here are the key principles of mindfulness and how to start a meditation practice.
