Don’t get distracted by shiny objects - Ray Dalio

Understand that a great manager is essentially an organizational engineer.

While in the past I would encounter problems, figure out their causes, and design my own ways to get around them, others who think differently than I do will make different diagnoses and designs. My job as mentor was to help them be successful at that.

Experience taught me how invaluable it is to reflect on and write down my decision-making criteria whenever I made a decision, so I got in the habit of doing that.
