"There are infinite moving parts within the world. This means the accidental impact of actions outside of our control often have a greater influence than our conscious decisions."

Work hard and take risks but also consider the role that luck plays in our lives and especially in finance. Focus less on specific individuals and case studies and more on broad patterns.

This should also help you develop greater humility when things are going right and compassion when they are going wrong.
