I'm reading a few posts that suggest "I don't want to 'think tactical' because it will ruin my enjoyment of the restaurant" or "It will make me think negatively all the time, looking for bad guys".
I contend - If you heighten your awareness, you not only keep an eye out for dangerous people and things, but you also keep an eye out for good and positive people and things.
Those people that drive around texting not only miss the pedestrians they're about to run over, they also miss the beautiful scenery, the pretty girls, the cute dogs etc.
Don't cross the street without looking for cars. Don't do anything without looking for a potential problem. That doesn't mean stay locked up in your bedroom. That means look around. ENJOY the good stuff. BE AWARE of the potential bad stuff.
