While I would say that it is more common for people to plan too little than to plan too much, I think that point one here is worded so strongly I would disagree. Most plans don’t even consist of entire sequences of actions, even for very small simple tasks such as writing this comment, during which I took multiple unplanned actions including noting that I took them, none of which would have been worth planning for.
Plans have a level of granularity beyond which you don’t plan in advance. As I said in another reply, stopping at the correct regularity is important and sometimes difficult.
