Early in my career as an analyst, I read the book Principles by Ray Dalio that outlined a series of principles used in both life and work to make decisions. These series of principles weren't groundbreaking in of themselves, but it inspired me to adopt a series of principles from the book and develop my own principles.
Other strategic leaders have adopted their own method for gathering and recording knowledge. Charlie Munger collected a series of human biases and referenced them constantly. He was certainly the best of his generation and I fear that we will not see a business leader of his caliber again in our lifetimes. Thomas Jefferson collected his wisdom in Poor Richard's Almanac. Even Marcus Aurelius wrote Meditations for his own benefit and didn't intend it to be published so widely.
In the past decade, I have collected and developed a series of principles that are useful in guiding my decision-making. These principles are written in a notebook where I have the freedom to draw and illustrate concepts that are difficult to write in a paragraph or blog format.
I welcome your feedback as you explore a few of the principles that I share publicly.
