I am recently trying to do this as a coping mechanism, especially at work. I tried this the other day and it actually helped me. It may be harmful in the long run, but in the short run it seemed to help. I was getting fussed at over something so trivial. I tried a technique I called "I will put this issue on a shelf and deal with it later." Then I walked away from the fussing and continued my work without falling apart, crying, and getting upset. It helped. In the process I think I upset a couple of co-workers but I kept my emotional stability intact and was able to function on the job. I have to try different things to work in an atmosphere of bullying and intimidation.
