When we're determined to reach an objective, it's the gap between where we are and where we aspire to be that lights a fire under us. - Adam Grant

Entrepreneurs who kept their day jobs had 33 percent lower odds of failure than those who quit. If you’re risk averse and have some doubts about the feasibility of your ideas, it’s likely that your business will be built to last. If you’re a freewheeling gambler, your startup is far more fragile. Like the Warby Parker crew, the entrepreneurs whose companies topped Fast Company’s recent most innovative lists typically stayed in their day jobs even after they launched. Former track star Phil Knight started selling running shoes out of the trunk of his car in 1964, yet kept working as an accountant until 1969. After inventing the original Apple I computer, Steve Wozniak started the company with Steve Jobs in 1976 but continued working full time in his engineering job at Hewlett-Packard until 1977. And although Google founders Larry Page and Sergey Brin figured out how to dramatically improve internet searches in 1996, they didn’t go on leave from their graduate studies at Stanford until 1998. “We almost didn’t start Google,” Page says, because we “were too worried about dropping out of our Ph.D. program.” In 1997, concerned that their fledgling search engine was distracting them from their research, they tried to sell Google for less than $2 million in cash and stock. Luckily for them, the potential buyer rejected the offer. This habit of keeping one’s day job isn’t limited to successful entrepreneurs. Many influential creative minds have stayed in full-time employment or education even after earning income from major projects. Selma director Ava DuVernay made her first three films while working in her day job as a publicist, only pursuing filmmaking full time after working at it for four years and winning multiple awards. Brian May was in the middle of doctoral studies in astrophysics when he started playing guitar in a new band, but he didn’t drop out until several years later to go all in with Queen. Soon thereafter he wrote “We Will Rock You.” Grammy winner John Le

A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die.

When we find out we might be wrong, a standard defense is “I’m entitled to my opinion.” I’d like to modify that: yes, we’re entitled to hold opinions inside our own heads. If we choose to express them out loud, though, I think it’s our responsibility to ground them in logic and facts, share our reasoning with others, and change our minds when better evidence emerges.
