As an individual who thinks that one should work to live, and not the other way around, it's pretty difficult to live in a contradiction where you know more money will give you more peace of mind and the possibility to retire early from the classic job schedule, and maybe live a more peaceful life, to enjoy more of what makes you happy.
Most of the times it's a balancing act between all of those factors, and as we age, we tend to change the way we see things moving forward.
"Having it all" is also a state of mind, some people just can't get enough, and that's how they will never be happy, no matter what and how much they have and accomplish.
