It's not true-- that negative feelings serve no purpose. If anything, they're usually trying to tell you something.

[Maybe ignoring them is how the Ashen Demon coped all this time, but it doesn't have to be like that here, even if it might seem in the short term like it makes things easier. He casts about for how to best explain.]

For example... Let's say you're nervous about something, or even scared. Those nerves can help you prepare thoroughly for whatever it is you're worried about, right? That kind of caution can save your neck compared to someone who's reckless or overconfident.
