Logs are there for those WTF!? Moments. When something unexpected happen and you don't know what. When you need a clue any clue.

Logs are there for observability, so you can get those, "Oh wow! Cool!" moments when you see something that you never knew.

If you never make a mistake, or if you know your external systems and uses perfectly.... Don't log.

If you're a mortal that gets surprises... log.
