If you could eliminate one emotion (anxiety, sadness, jealousy, regret, etc.), would you do it? Why or why not? If so, which one would you choose?
I'd never eliminate an emotion. By theory, it sounds splendid to eliminate the bad things, but once we only have the good things, wouldn't the good-feeling dissipate after some time?
I believe the sense of emotional response is part of living. I remember in my philosophy ethics course, my prof discussed this topic. He explained it as each of us being hooked up to a machine that would give us pleasure in every kind of way imaginable. If we only needed to hook up to a machine to feel ecstasy, what would be the purpose of having the things around us? We'd almost be numb, and it would be similar to a comatose-like state. That is not what living is.
I would not want that, especially being a person who likes to write. Not the best of many people's writing involves just wonderful circumstances. Typically writing involves an array of emotions. People need to experience both positive and negative emotions to appreciate the flow of fuzzy feelings. To cry, to become angry, to smile, to become enthralled-- all of these are essential to living.
