I find trying to hide and wash away emotions tends to be a dangerous strategy long term. I get that sometimes emotions are unproductive for the task at hand, but the longer you keep washing them away with "logic", the stronger they keep returning at inopportune times. The long term strategy that works for me is to acknowledge them, actually listen to them, but also recognize I have the ability to act despite them. Easier said than done of course.
My use of "wash away" is more like "transform from unstated feeling to stated feeling with new analysis minimizing bias, for future decisions". It's not a suppression, it's a making stated what was unstated before. It's an attempt at self honesty.
Ah fair enough, that wasn't completely transparent to me.
"Fighting and hiding emotions is counterproductive if your goal is clarity and internal harmony" is a life-lesson that took me all too long to learn, so I'm a bit militant about pushing back on the "fight/hide/ignore" approach to this.
