One of the things I’ve learned in taking up my course (BS Psychology) is the skill of shutting down my emotion/s in something or in someone. We had training for that in preparation for the possible career in Clinical Psychology. In guidance counseling or in clinical therapies, psychology practitioners should not feel any attachment to his/her patient and the process for them to asses objectively and professionally, to be effective. It has advantages and disadvantages if you have that skill.
One of the many advantages of that skill when used in day to day life is that you can assess results and re evaluate the next plan without having emotional set-backs…or in other words, getting hurt. If you don’t get what you want, or things doesn’t go your way, it won’t affect you and just move on after re evaluating the situation.
