Security, we all want. For our homes, for the goods and persons in (and cats, of course). To be safe as much as possible. There is financial security, or at least they say so, must be true. Eight people seem to know what that is, so it is not a unicorn term.
The first we worry about probably, especially in today’s world, our personal, physical security. On streets, we have not much of a control over, so we do our very best to take that control to home. That is our castle. And home starts with securing the most evident first (but not only that alone): the front door.
There is tech to help you: smart locks with smart phones, cameras, alarm systems, pit bulls, psychotic neighbor. Or a combination of these tools. You can make it as expensive as you wish, it is in the name of freedom, your choice to go broke on the way you want. OR, you do what Elayne Boosler shared once about entrance security:
I have six locks on my door all in a row. When I go out, I lock every other one. I figure no matter how long somebody stands there picking the locks, they are always locking three.
