Organization is not a trivial issue.
Being unable to locate an item is stressful. It drains energy. You become worn out from emotional turmoil. It can easily make the difference between success and failure.
The first step in getting better organized is to acquire adequate shelving for books and miscellaneous items. You also need drawer space for files and smaller items. A good desk is helpful.
The key to organization is that each item should have a home. Think of a carpenter’s workshop where every tool has its place. When you notice something is not where it belongs, you should immediately stop what you’re doing and put it away. If you accept these simple principles, you will see a dramatic change in your life.
