Camille Sweeney and Josh Gosfield write on the value of self-awareness for success:

The successful people we spoke with — in business, entertainment, sports and the arts — all had similar responses when faced with obstacles: they subjected themselves to fairly merciless self-examination that prompted reinvention of their goals and the methods by which they endeavored to acheive them.

The tennis champion Martina Navratilova, for example, told us that after a galling loss to Chris Evert in 1981, she questioned her assumption that she could get by on talent and instinct alone. She began a long exploration of every aspect of her game. She adopted a rigorous cross-training practice (common today but essentially unheard of at the time), revamped her diet and her mental and tactical game and ultimately transformed herself into the most successful women’s tennis player of her era.

The indie rock band OK Go described how it once operated under the business model of the 20th-century rock band. But when industry record sales collapsed and the band members found themselves creatively hamstrung by their recording company, they questioned their tactics. Rather than depend on their label, they made wildly unconventional music videos, which went viral, and collaborative art projects with companies like Google, State Farm and Range Rover, which financed future creative endeavors. The band now releases albums on its own label.

This is great, but it all comes with the benefit of hindsight. This kind of advice isn’t useful to the person still struggling with their business, personal goals, or indeed anything worth pursuing. But if you found the advice useful, the authors have a book to sell you.
