Minimize your cognitive load from distracting things that don't really matter; it's hard to overstate how important this is, and how bad most people are at it.

Maintaining a focus on the most critical problems rather than getting distracted by less important issues can lead to more effective problem-solving and better outcomes for the team.

Rationality in decision-making is often misunderstood; we don't always process information dispassionately due to inherent brain constraints and the concept of bounded rationality.

The design of our brains allows us to prioritize attention efficiently, which is crucial for navigating our environments and making decisions.

Focusing on first principles is crucial; understanding the actual problem we are trying to solve allows for more tactical and effective solutions.

It's crucial to understand the challenge you face, not just the world around you. The diagnosis should focus on what makes the problem hard.

The mind excels at solving new problems with clear parameters but struggles with making difficult decisions that lack defined edges. When faced with a hard decision, it's beneficial to ruminate on it, then sleep on it for a couple of days until a gut answer appears with conviction.

Deliberate deoptimization involves choosing in advance what to neglect, allowing focus on what truly matters.

First principle thinking is essential; it involves breaking down problems to their fundamental truths and building solutions from there, rather than relying on assumptions.
