Imagine lying in bed, laptop open, typing an apology to a client because your body has completely given out — a full allergic reaction on top of a car accident on top of a shoulder that can't lift above your head. You're 48. A UC Berkeley researcher. A mother. And for the first time in your life, you're turning down work.
Kara Sammet grew up with one foot in two very different worlds. Her mother — a single mom on public assistance — stretched every dollar, chose between bus fare and macaroni and cheese, and built herself into a CPA with a 4.0 the same year Kara graduated middle school. Her father's family, meanwhile, skied in Aspen. The message Kara absorbed was sharp and clear: your safety depends on your ability to earn. Work hard, save everything, never go into debt. And never make too much money — because people with money think they're better than you.
She carried that drive all the way to a PhD in educational statistics, a research post at UC Berkeley, and a seat at the table with tenured faculty from Harvard. She was doing important work — helping tech companies like Google, Snap, and Cisco bring more women into leadership. But it was soft-money contract work. And she was running herself into the ground.
At 48, her body staged a revolt. Shoulder injury. Constant illness. Nearly 50 extra pounds. A doctor who shrugged and said: "You're almost 50. That's just what happens." A yoga teacher who said: that's not true — go find a physical therapist. So Kara did. She paid that yoga teacher to walk a mile with her while she rehabbed her shoulder. She set a goal: run three miles around the lake by her 50th birthday. She did it. Then kept going — to triathlons, to 100-mile bike rides, to half Ironmans.
When the pandemic hit and her academic contracts dried up, she made the pivot. The colleagues asking "how are you doing what you're doing?" became her first clients. The behavior-change research she'd spent a career studying became the method. And Healthspan Habits was born — coaching high-achieving adults, especially women, from couch to consistency using neuroscience, community, and compassion.
Her definition of success hasn't changed at its core: do work that matters, and trust that financial stability follows. What has shifted is where she believes safety comes from. Not from external circumstances. From within.
