How could you employ the wisdom of the worry box? Whenever possible, catch a worry in its first few moments. Confront it with a rational or positive thought. Ask yourself what is really true. If you don't have the facts to answer, then plan how and when you will get them. For example, if you begin to worry about paying your bills, take the time to list specifically what you owe and then calculate available funds.
If worries take hold before you realize it, try escaping by doing something physical. Take ten slow, deep breaths. Go for a walk. Mow the lawn. Or you might create a beautiful vacation spot and go there in your mind.
If you don't have a "worry buddy," it is well worth finding one. This is a person you can call at any time, someone who can objectively help you put your current worry into perspective. Sometimes just talking about it will drive the worry away.
If worry still persists, sit down for an "okay, worry, let's have it" session. Worry as hard as you can, and then, when you are worried out, grab your notebook, ask yourself what you can do about the situation, and make work notes. Then take any leftover worry, about which you can do nothing, and place it in the worry box. Put the lid on and forget it!
