Never say never

So, if you haven't pursued your life's passion and dream by, say age 50, it's too late, right? Some would even say that's way too late.

Don't tell that to Barbara Beskind, however. She's a 90-year-old designer on the staff of IDEO, a Silicon Valley firm that develops innovative and creative things such as the first mouse for Apple. And she's only had this job for two years.

Beskind always wanted to be an inventor. But when she grew up, she was told she needed an engineering degree to do that, and those college departments were only open to men. So were those jobs. So she went on to a career women could have. After five careers and five retirements, she contacted IDEO after seeing a 60 Minutes segment about them wanting a diverse staff. With lots of 20- and 30-somethings on their staff, they did need some diversity. So she wrote to them—and they wrote her back just days later. The young staffers love her. She loves them—and loves working in such a creative and lively environment.

Her story really inspires me. I hope it does the same for you. Never, ever give up on your dreams. Always follow your passion. Beskind's advice: "Embrace change and design for it."

What would you still love to do—as a career, a hobby or just a one-off experience? Go for it!
