I don't get in fair fights, they are too easy to lose.
I don't go walking down dark alleys at midnight.  I know where not to be and when.  I have decent situational awareness, know what is around me, and while overtly my head is not on a swivel, I do keep tabs of my surroundings.  I am not above beating feet should the need arise.  I fight only as a last resort, but should the need to fight arise - I will use anything and everything at hand to ensure I walk away.
The best fight is no fight.  The second best is the one you walk away from.
