Do the simple shit first.  Then worry about becoming John Wick.

Start with what you know you should do and the advertisements you see everywhere that you ignore.

Lock your doors and windows at home all the time Lock your doors, take your keys, and hide your belongings in your car, all the time, every time. Go places in groups and with a friend Look up from your damned phone  Move with a purpose  "Don't do stupid things, with stupid people, in stupid places" -John Farnam "At stupid times" - Bob Mayne 

Stay Safe,
