Minimalism is not the end game; it is not the result. Chucking your material possessions does not necessarily equal happiness. You could get rid of all your stuff and still be miserable.
Getting rid of the excess in your life will, however, help you discover what does in fact make you happy. (Hint: it’s not your possessions; most of your possessions are actually in the way of your happiness.) And it’s much easier to find the path toward happiness once you’ve cleared the debris.
Minimalism will never lead you to your utopia. Life will always have its moments of tedium and drudgery and sadness and pain. But minimalism can lead you to a better life, one that’s more exciting and fulfilling and satisfying and rewarding—a more meaningful life.
