If you watched the video, he goes into a discussion about shocks (about 8 minutes in) like bad investments but how they don't really matter as much if r (rate of return) is greater than g, the rate of economic growth. If r = 5% and g = 1%, then you can lose 80% (the difference) and still be ahead because the return on the remaining 20% has paced with economic growth.
Right now we have five, but we’ll probably cut that down to four at ER next year. Current: W-2, business income, rental income, interest on personal loan plus accounts, dividends and cap gains. Future: subtract W-2 for the most part, not counting little “fun work” projects. If we were looking to live the high life, we might aim for the millionaire’s seven sources, but we feel like our four sources will let us live very comfortably with plenty of contingency plans in place. 🙂

Ethiopia’s economy experienced strong, broad-based growth averaging 10.3% a year from 2005/06 to 2015/16, compared to a regional average of 5.4%. According to official statistics, Ethiopia’s gross domestic product (GDP) is estimated to have rebounded to 10.9% in FY2017. The expansion of agriculture, construction and services accounted for most of this, with modest manufacturing growth. Private consumption and public investment explain demand-side growth, the latter assuming an increasingly important role.
How To Engineer Your Layoff – In 2012, it took me four months of absolute focus and two years of data to publish my first e-book about helping people negotiate a severance. The book went through over 30 revisions by four people. Then I updated the book for 2018 with 50 more pages (150 pages total) using more successful case studies and highlighting more strategies for those who want to break free with money in their pocket.
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
