Blankfein advises leaders to study history for pattern recognition. He notes that rereading a biography 40 years later gave him a new appreciation for the subject's achievements, showing how personal experience reframes your understanding of the past.

Ken Griffin advises that graduation marks the beginning, not the end, of education. He argues the most important skill is learning how to learn, as professionals will need to develop entirely new toolkits multiple times over a 40-50 year career to remain relevant amidst technological change and increased longevity.

Jeff Aronson credits his success to a mental shift early in his finance career. While taking night classes, he realized he was studying to genuinely understand the material, not just to earn an 'A'. This transition from extrinsic validation (grades) to intrinsic curiosity is a key differentiator for developing deep mastery in any field.

Following Nietzsche's "monumental" approach, history’s value lies in finding figures whose greatness resonates with your own potential. This shifts the focus from memorizing facts to seeking inspiration for your own life's path, much like Julius Caesar was inspired by Alexander the Great.

Don't just read the latest business bestsellers. To develop true judgment, read old books that have stood the test of time on topics you know nothing about (e.g., Roman history, biographies). Time filters out noise, providing pure signal and building diverse mental models for decision-making.

To maximize signal over noise, prioritize reading books that are decades old. Time acts as a natural filter, weeding out transient ideas and elevating timeless principles. This is a more efficient learning strategy than consuming popular, contemporary business books that may not have lasting value.

True wisdom isn't about accumulating information (an additive process). It's the more difficult act of subtraction: editing our minds, rethinking assumptions, and removing outdated beliefs. Nobel-winning breakthroughs often come from this kind of subtractive editing of our collective knowledge rather than a new addition.

Famed banker S.G. Warburg believed studying classics, history, and philosophy provided better preparation for finance than modern economics. He argued it develops logical thinking and a deep understanding of human nature, which is the true core of the business. For Warburg, progress in thinking was progress toward simplicity, not complexity.

Most people learn things "just in case" they might need them, like in university. The most effective approach is "just-in-time" learning—acquiring knowledge from books, courses, or mentors to solve a specific, immediate challenge you are facing right now.
