chakster,
You got me. I was really just playing with simple numbers to see how good of a business it would really be. I had no firm agenda or message behind it.
Now, you made me think what the moral of the story/calculations would be. I think I would want to say "There are more efficient ways to become a millionaire". Someone may like it, but 66 000 of whatever money a year is a very slow way to a millionaire. The trick is that being a millionaire is not what it used to be. Take U.S.A. as an example...
- Full-time working men in 2019 had median earnings of $57,456
66 000 a year is less than 20% more than that median income.
I am sure examples you gave have done well, but it is a lots of fine work, apparently it has to be a number of people/employees involved, organization, etc. And with all that effort, 15 years and lots of luck to get above median earnings. For the love of it, a person can get lucky and enjoy, but as a career choice, there are more reliable ways to become a millionaire.
