A lot of investing conversations focus on expense ratios, taxes, and transaction costs.
But I think behavioral costs matter just as much.
Panic selling during volatility.
Chasing narratives after huge moves already happened.
Constant portfolio switching because of headlines.
Checking positions every hour during drawdowns.
Those decisions slowly compound into performance drag over time.
The funny thing is that many long-term investors would probably outperform simply by reducing emotional reactions instead of constantly searching for better entries.
The market punishes impatience more consistently than it rewards intelligence.
