Considering tactical insights

I want to provide general tactical insights framed as possibilities, without coming off as assertive or spreading misinformation. I think a list of 1 to 3 options could work well here. By using terms like "common reasons" or "potential turning points," I can keep it vague enough while still being helpful. Let's make sure to keep the tone open-ended to encourage exploration! This way, I’m ensuring more flexibility and clarity for the user.
