Jony Ive, Apple's former chief designer, reveals that working with Steve Jobs for nearly 15 years, including daily lunches, taught him the critical lesson that curiosity trumps certainty. Ive, who co-designed iconic products like the iPhone and iPad, states Jobs' 'insatiable curiosity' was his defining trait, even after achieving monumental success. Jobs prioritized learning over being right, exploring ideas freely in the design studio.

This mindset, Ive argues, was fundamental to Apple's creation of products that sold over 3 billion iPhones and built a $4 trillion market cap company. The lesson extends beyond Ive; leaders like Tim Cook and Brian Chesky credit Jobs with shaping their philosophies. Cook noted Jobs valued evolving beliefs and lively debate, while Chesky learned Jobs partnered, not micromanaged, fostering talent.

Even Corning's CEO Wendell Weeks credits Jobs with confronting his fears, leading to a $2.5 billion deal for iPhone glass production. Jobs' relentless curiosity, Ive concludes, was the secret sauce uniting talent and enabling terrifyingly new innovations.
