Calling a physical object minimalist is erroneous, because things change. States are temporary. Just because it is minimalist now doesn't mean it will be in ten minutes, or a day, or two seconds. A clean desk is never a clean desk forever.
Minimalism is an action, a collection of verbs that describes how we do things and why. It says that we reject the prescribed notions of complexity and the burden of the rat race in search for a more personal, focused experience.
The verbs with which you choose to fill your minimalism bucket are your own, not mine, not some other blogger's, but your own.
-Use Linux (surprise!)
-Eliminate for the sake of focus
-Rarely, if ever, buy new technology-related products
-Pride function over form, but realize that the two can be harmonious*
-Create rather than consume
-Learn more, constantly and forever
-Help others around me learn more, constantly and forever
*A good example of this principle is how the only thing I have plugged into sockets in my room is my alarm clock and a single power strip, which is stuck out at an easy-to-reach position in the floor. If I want to charge something or use my CD player, turn on the strip. It's all easy to access, easy to turn off, and saves electricity. Sure, it looks kind of ugly, having cables all over the place, unhidden, but it makes my life tremendously easier.
