I’d probably set a motivation goal instead.
IF you want 40 million dollars of my inheritance
THEN you must be able to make 75,000 dollars gross pay per year, indexed against inflation, in the field of your choice. Indicate that field here —> ___________
You must then work 10 years in that field successfully, utilizing a standard 40 hour work week (minus, of course., vacations (2 weeks) and standard bank holidays), amassing a minimum of $200,000 cash on hand.
If you are found to have conspired with any person or business to fraudulently receive the required salary in order to share the inheritance with either the person or the business, you will forfeit the entire inheritance. Your work history will be audited on an ongoing basis, and certified by (choose a big-3 Audit firm).
I know tons of people that make $75K a year.
I know zero people that saved $200K in a decade.(With $75K as income)
I’ve set up a simpler version of that. The kids get an initial sum. If they increase their net worth, they get the remainder. If they don’t, they get the remainder in installments over time. (My kids are all financially independent.)
