When you know what you have, where it is, and that it can be easily retrieved, you don’t spend precious time looking for things, being frustrated trying to get to them or worrying you are forgetting something. When everything is in its place, you are not distracted by what is around you, you can focus on what is important and be present in the moment. You feel prepared and on top of things, which makes you calmer and happier in all areas of your life.
