Something that I have found to help combat that problem in my life is to simply force myself to do something! Sometimes I will tell myself "I only have to work on this for 15 (or 30... whatever) minutes". And then I will set the timer and work on it for that long and then often when that amount of time is over I have found that organizing job actually to be kind of fun and I keep going or sometimes I will quit and then at some later time I will work on it for a while again.
Doing something helps us to make a little progress - we have taken the first step and the journey isn't so hard after that.
I did that when I was working to get my e-mail inbox organized, I am currently working little by little through all of my digital pictures to organize them. When my office/crafting area needed a lot of organizing and felt very overwhelming I just tackled a drawer/shelf at a time and eventually it was so much better!
To get something done you just need to take the first step!
Have you found this concept helpful in your life? Any organizing tips that you would like to share? I would love to hear them!
