When it comes to organizing, sometimes you just need to jump in and start. Whether it's a pile of clothes, a pile of papers, or you can't see the floor anymore because there's so much stuff covering it, thinking about what the first move should be can be overwhelming. And if you think about what you need to do for too long, you can become stricken with fear about making the wrong move, thus causing you to do nothing. This, my friends, is what I call analysis paralysis. I've encountered it myself.
When looking at a client's workspace that needs a lot of help, I want to make the most efficient moves. I don't want to have to re-do anything, and the containers that I use need to be the most effective for that client. However, I have caught myself analyzing the situation over and over in my head, sifting through many different possibilities, to the point of not making a move on any of them. Once I'm cognizant of this, I then force myself out of this by just moving my body towards a corner of stuff, and begin work. Then the answers come to me more easily.
Physical movement can shake us out of paralysis, and free us from the fear of doing something incorrectly. Because, frankly, nothing is permanent, or wrong, when it comes to organizing. Do your best, and know that you're at least doing something, working towards a positive goal!
