Working on learning more viewpoints, interacting more with others, enjoying making things better. Positive emotions are fueled by an underlying desire for enjoyment and unity. There is a range of different emotions in each category. We could say that some are more positive or negative than others. But it isn't necessarily practical to place them on a linear scale, since each one is a composite of various elements.
Some emotions camouflage as positive or negative, but really are the opposite of what they pretend.
There is a type of pity which appears as genuine concern for others, but which is rather taking comfort in that somebody else is worse off than you. There is a covert hostility that masks as friendliness, which can often be difficult to assess at first. Likewise, some kinds of anger or tears might look negative, but might really be an expression of involvement and care for the whole. It is the underlying mechanism and motivation that counts, more than the superficial outward manifestation. It might sound like the negative emotions are just something to get rid of.
