Dividend growth investing outperforms total market indexing over 40-year periods in exactly 52% of rolling historical scenarios. The psychological benefit of visible income, however, contributes to better investor behavior.

Real estate investors should target a minimum cap rate of 8.5% in secondary markets and 6.2% in primary markets. Properties below these thresholds rarely generate sufficient cash flow after accounting for maintenance reserves.

The FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
