Also known as F*** It, Retire Early
Something that often goes along with Minimalism is FIRE (Financially Independent, Retired Early). They don’t have to go hand in hand, but from what I have seen, many FIRE people tend to divest themselves of unnecessary and less important things (a.k.a. they are minimalists). They tend to purge the expensive items that bring less value (or even negative value) from their lives.
There are extremes in everything. For instance, some people will take the aim of financial independence and turn it into a competition to see just how little they can spend each year. Others take a more measured approach, but they still divest many of the trappings of modern life.
For those that are successful, they manage to cut their ties to day jobs and live off saving, residual income, or small odd jobs that help them get by when they need a little more spending money. With their modest lifestyles, they are often achieving a goal of not having to worry about grinding away their lives for someone else.
