Let’s use Jim from our personal finance example. Jim’s furniture manufacturer builds tables and has several large pieces of equipment in the sawmill used to re-saw logs and boards down to the finished dimensions. The sawmill has net operating revenues of $100,000 for year. The saws in the mill cost Jim a total of $500,000 and he is currently earning a return of 10% in his wholesale table business. Thus, he sets a minimum required return of 10 percent.

Hello from the UK! Fundrise and Wealthfront are only available to US residents it seems :(. Any other readers from the UK here? The only thing I have managed to do from Sam’s list is getting a fixed rate bond (CBS is having a 5-year fixed rate at 2.01% – not great but the best I could find ). Don’t know if the FIRE movement will ever take off here but would love to trade tips/ideas on how to reach FI and have the freedom to consider alternative rythms to living.
One of the most appealing options, particularly for millennials, would be #12 on your list (create a Blog/Youtube channel). The videos can be about anything that interests you, from your daily makeup routine (with affiliate links to the products you use), recipes (what you eat each day) or as you mention, instructional videos (again with affiliate links to the products you use). Once you gain a large following and viewership, you can earn via Adsense on YouTube.

Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
