On a serious note, this effect can be applied to our everyday problem as well. Such as when you are feeling lethargic, you'd want to write down all of your thoughts in a list to see the bigger picture and figure out how simple it can be to finish a task at hand.

s/lethargic/anxious/, and I do this all the time! Doing a quick mind dump usually clears out my anxiety, or at least reduces it to a manageable level, allowing me to continue doing things.

You should check out the book "Getting Things Done", which is based on taking what you described and using it to stay organized and adaptable. If you've got anxiety it would probably help at least a little bit.
