In this special episode of Excess Returns, we share the most important investing lessons from more than 50 of our top guests. After asking more than 200 investors, strategists, academics, and market thinkers the same closing question about the one lesson they would teach the average investor, we compiled the most powerful, timeless, and repeatable insights into a single episode. This collection highlights common themes around patience, discipline, humility, diversification, risk management, and long-term thinking, while revealing how great investors navigate markets, behavior, and uncertainty.

Main topics covered:

• Why investing is about preserving and growing wealth, not getting rich

• Why neither get in nor get out is an investing strategy

• The role of base rates in decision-making

• The dangers of performance chasing

• Why you should look at your portfolio less often

• The importance of independent thinking and avoiding envy

• Treating stocks as businesses, not trading sardines

• Diversification across assets, strategies, and economic regimes

• The behavioral traps that destroy wealth

• Liquidity, supply and demand, and how markets really function

• The value of patience, long-term thinking, and sticking to your plan

• How to build a resilient portfolio that survives different market environments

• Why simplicity often beats complexity

• The role of humility, self-awareness, and keeping emotions out of investing
