You aren’t obligated to feel any emotion that doesn’t win.
But it’s really hard to tell which emotions one should or shouldn’t feel in order to win, and part of the problem is that feeling emotions can cause our consciously held values to change, in a way that we don’t fully understand and can’t accurately predict.
Perhaps this is why some people seek out clear moral principles, so that they can commit to them and thus stop their values from drifting uncontrollably.
