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,
