Emotions are difficult. Sometimes "I am feeling this and it is important" can be helpful. Sometimes "I am feeling this, but it is at odds with what I would like to have happen" can help. Really depends on the specific situation in a lot of cases.

Attempting to be Vulcan was not ultimately helpful to me in the long term. I believe that my good friend Purple tried a similar trick. It similarly failed to do good things in his life, though I am sure it must have been temporarily useful.
