It also shows clearly why the median and the mean of the asymmetrical log-normal, even more so for a power law, differ and represent threshold conditions. One does not have to get into the mathematics to see that averages in an asymmetrical distribution do not convey the same degree of the “typical investor behavior” that they convey in a symmetrical distribution. How do you optimize your practice for the average investor if your own investor income and wealth data follow such an asymmetrical distribution?

None legally required, but 7-21 days is standard for most employers. Typically, 10 working days. Many U.S. companies give only one week, and then frequently only after completion of a year of employment [e]. A recent United Nations survey indicates the average number of vacation days actually taken to be of 13 per year [f]. This corresponds to the fewest vacation days amongst advanced economies.
Whether you take a “distribution” (aka free-cash-flow) in the form of a dividend, interest payment, capital gain, maturing ladder of a CD, etc, you are still taking the same amount of cash out of your portfolio.

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.
