Hope for the best; plan for the worst and be prepared to die for what you stand for. What else is there to say?
Protect the weak and those that can not defend themselves against those that seek to prey upon them.

"When it takes multiple shots" by MASSAD AYOOB
When it takes multiple shots – Personal Defense World <Read it all here.
In the Chicago area engaged multiple police officers in a hellacious shootout. I was told by a member of the investigative team that the guy was a heroin junkie who had recently “shot up.”
Thus, it’s no surprise that this man took a whole lot of lead before he stopped trying to shoot the officers. He was shot 33 times with 9mm pistol bullets before he went down. I’m told he was also hit with two 12-gauge rifled slugs, the second of which at last ended the fight. The suspect has been hit many times in the head, and virtually all of his body organs have been violated by bullets. However, none of the headshots reached deep brain. A part of this “stopping failure” may have been the choice of ammo, reportedly 100-grain “soft-nose” rather than hollow-point bullets, most of which passed through and through without expanding. But a huge part of it was obviously the drugs the gunman had on board.
Shot Placement
The most important factor in the nebulous topic called “stopping power” is shot placement. In Case Four, a lawsuit alleging excessive force and wrongful death was filed in the wake of a “suicide by cop” in suburban Illinois. After what was later established to be a classic pre-suicidal “departure ritual,” a man staged a disturbance he knew would draw several police officers. When they arrived, he attacked them with a bludgeon. With two officers down and injured, the third opened fire. He was armed with a high-capacity 9mm semi-auto carrying 18 rounds of 115-grain 9mm Silvertip ammo.
Compassionately trying to stop the man without killing him, he fired his first several shots into the man’s legs. But they didn’t stop him and he kept coming. The officer raised his weapon to the man’s chest and kept shooting, though the suspect’s violent swinging brought his arms in line with the blazing service pistol as often as his thorax. When the assailant finally collapsed, the officer’s 17-round magazine was empty and only one cartridge remained in the chamber of his pistol.
The dynamics of the shooting were explained extensively in court. The officer who fired was personally exonerated, and he was the first to determine that “shooting to wound” was the biggest reason his initial gunfire had failed to stop the attacker.
Over in Seconds
In any shooting case, including those cited above, the jury has to be constantly reminded of how fast these things happen in real life. It always takes longer to explain what happened than it took for the incident to happen. This creates the false illusion of it having happened in slow motion, with all sorts of time for you to explore options and perhaps do something less drastic than shooting an attacker several times.
And don’t forget that jurors have spent their lives watching slow-motion shootings on TV and in theaters.
In a courtroom, the very few seconds of your incident are dragged out over days, weeks, or sometimes even months of testimony. It’s easy for those who judge you to start seeing the event in slow motion—so it is critical for your defense team to constantly bring the jury back to the unforgiving speed at which your incident took place. They need to understand what little time you had to react.
