The problem is that "their life" is so much a part of "youe life" (for the poster above you). Good relationships with other people are a huge part of what makes life better. I've always imagined that if I ever get FU money that it would allow me to live closer to people I have good realtionships with.
I have near life long friends who I still see regularly enough but several of us live in different states / countries now. I wasn't implying that they should alienate themselves from their friends but they shouldn't make drastic changes to their life just to accommodate them. ( I consider changing your lifestyle + moving to a new location a 'drastic' change ) One the best things having FU money allows for is the ability to 99.9% of the time decide to travel to X at 1pm on Tuesday and be on a plane to X by 4pm the same day.
