Some of my clients have a lot of difficulty visualizing how they are going to finish organizing because they feel overwhelmed and defeated. I say let them eat cake!
Have you ever tried to bake a cake without a recipe? Maybe those geniuses on Top Chef could do it but I need specific instructions on each step from ingredients, to mixing order, and even how long to bake.
The same is true for organizing, you need to break down the big picture into appropriate steps, from supplies to placement. So the next time you feel paralyzed by a complex task, break it down into bite size pieces and soon you too will be eating cake!
