When the Coronavirus first struck the U.S., Julia Cheek was in an unusual position of being one of the few people on the planet able to do something about it. 

As the founder of Everlywell, an Austin, Texas-based maker of at-home, diagnostic-testing kits for sexually transmitted diseases, vitamin deficiencies, and food sensitivities, Cheek quickly pivoted her business to start offering Coronavirus test kits. The transition was acccompanied by considerable difficulty. As Tom Foster wrote in Inc.'s May/June issue cover story, Cheek faced pushback from the U.S. Food and Drug Administration. Her persistence finally paid off on May 16, when Everlywell was granted emergency use authorization from the FDA, a first for any digital health company since the pandemic began. 

"There are on any given day a thousand problems I'm solving...that actually will result in failure," says Cheek about developing the business during the covid-19 pandemic. "But that is not what I need to do," she says. "I need to solve the one or two problems that are the most important to solve to help the business succeed."

This ability to focus and then refocus as needed is the key takeaway from this week's episode of What I Know, featuring Cheek.
