How Do I Stay Aware of What's Around Me?

My wife is a pharmatist, and despite having had her pharmacy broken into twice after ours, she has some pretty terrible habits. For example, she to her car at night with headphones on, almost never locks our house or doors at night,. In general lacks the ability to orient herself to her surroundings. I find it difficult to get my point across when i suggest ways to stay safer and prevent finding herself in a bad situation. How would you approach this discussion? Please share your thoughts below.
