I started a Dialectical behavioral therapy class. It is 3 hours a day m-th. We are talking a lot about emotional management. Sometimes emotion comes in huge waves and we need to know how to manage.
Apparently you should be able to deal with pure emotion in 60 seconds. The reason they usually last longer is because of secondary emotions. Like for example someone cuts you off on the street , first emotion is fear then maybe anger and frustration. I think I have had the 60 second experience before and the secondary emotions also.
