Get rid of a bit of stuff and I guarantee that everything will feel a bit better for a while. The idea of creating more space in your life is a good one - most people would benefit from having less stuff, crap, things, gadgets and gizmos.
When I am creating more space in my life I like to concentrate on the space freed up, not the stuff I am getting rid of. Ultimately, the space I am freeing up is in my head, not my closet.
Less stuff = less thinking about stuff. Less thinking about stuff = more thinking about the things that are truly important. Or not thinking at all.
Most stuff is toxic and should come with a warning label.
Warning: This item is toxic to your environmental space, physical space and mental space.
After establishing your de-cluttered Nirvana, prevention is the key. Be very, very selective about what kind of crap is allowed to enter your space. I treat every potential purchase with a critical eye, looking for the hidden (or not so hidden) downsides. Then I consider the Stuff Rule #1.
Stuff Rule #1 - there are always downsides.
Get rid of it. You WILL feel better. Then be militant about not allowing more in. Your freedom is worth it.
