I've said this before and I'll say it again. There is nothing wrong with experiencing all emotions, only with letting them overrule rational thinking and the happiness. I'd rather be determined than angry, rather contemplative than depressed, rather accepting than grieving, rather improving myself than ashamed, etc.
Shame caught my eye on that list; a disgusting emotion that implies that one has failed themselves and is solely used to crush spirit.
In my mind that mountain must be a bit different, because every time you go down it, you feel the negative sides of emotions instead of the positives. For example, let's examine the emotion that creates drive: anger/determination. Anger is the negative form, raw and rampant; determination is the positive, more constructive shape. Sometimes you just have to let it run wild and sour? I disagree.
Currently the state of human emotions can be drawn as a simple diagram:
Negative <---------- Emotion ----------> Positive
So that in the case of this which I label as "drive," it would be:
Anger <---------- Drive ----------> Determination
What I propose is that instead of making the formula partial, i.e.:
Drive ----------> Determination
We move along in the progression of emotion to a more advanced sensation where what we now consider to be the "better" alternative is in fact less useful/nice/glorious in comparison to the other one:
Determination <---------- Drive ----------> ? ? ?
Of course, as all emotions are mixed and tangled more often than not, it might be necessary to combine emotions to get the improvements. We've already had physical and cultural evolution, why stop there?
