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. For more on this topic, see Lifestyle Design Choices.

Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.
