Its time to fight when the situation is no longer acceptable to you. Rarely do you have to fight. Rarely do you encounter a situation that is truly unacceptable. The obstacle is not that you fail to choose to fight, for it is not a choice but a fact that when something is unacceptable to you, you will act upon it in some form. The failure comes in realizing too late, and then you are playing catch-up with your very life, when you are surprised or not properly prepared with a flexible and comprehensive self-protection doctrine, you are not given the opportunity to enter the fight. If so, your actions may be inappropriate or insufficient. Anyone can successfully negotiate personal violence as long as he is given the ability to act appropriately.
