TIL: I/NW

https://thefinancebuff.com/delayed-gratification-enough.html

I was reading this article and it introduced a simple model to make the deicison of when you want to retire.

EI/NW is the Employment Income To Net Worth Ratio,
And the other line is your requirement for the ratio to be. When they cross, that's when you stop doing it (for money).

The concept of I/NW is interesting because it measures income as the portion of your net worth, instead of the absolute value. It makes sense because that's also how you measure how securities' performance (by yield, APR, APY etc).

Another interesting thing from this article is that the required ratio is not fixed and people grow less content with how much % they're adding to the net worth as they grow older.
