"If you’re not comfortable going deep for extended periods of time, it will be difficult to get your performance anywhere close to its potential. Depth is to knowledge work what practice is to athletics: the essential environment in which you sharpen your abilities."

"Energy determines whether you can protect your focus."

"Productivity tends to diminish after a threshold of work hours, supporting the idea of diminishing returns and the need for recovery to protect focus."

"The more present we are in practice, the more present we will be in competition, in the boardroom, at the exam, and on the big stage."

"Great performers work in focused blocks followed by rest."

"Flow comes from complete concentration and clear goals."

"Regular rest improves the quality of deep work."

"High-quality work is produced by the amount of time spent multiplied by the intensity of focus."
