Reacher's Rules. Life Lessons From Jack Reacher

My name is Jack Reacher.
No middle name, no address.
I'm a man with a rule.
People leave me alone, I leave them alone.
If they don't, I don't.

As every Reacher fan knows, you don't have to break the rules if you make the rules.

Rule 1. Never volunteer for anything
Rule 2: Be on your feet and ready
Rule 3. Show them what they're messing with
Rule 4: Don't break the furniture
Rule 5: If in doubt, drink coffee
