if youre already reach and have one million dollar youre target incraese and say if one million dollar is small money
I guess that someone educated enough to not increase his target after achieving the 1M goal would be happy with this amount of money and that it would be, therefore, enough.
It is all about needs vs. boredom. If you don't have the money to cover your basic needs, you focus on covering these, while if you have more, you focus on ending boredom usually by trying to make more money in the hope that it will work.
The one who is not happy with anything won't be happy with everything, neither.
