Step 1: Gather a basic disaster preparedness kit for yourself and your household. This can include: water, non-perishable foods, cash, flashlights with plenty of batteries, blankets, fire starting devices such as lighters/matches, walkie-talkies, a small weapons cache
Step 2: Be sure to have simple clubbing objects/weapons within your reach, around your home, workplace, even in your vehicle
Step 3: If legally possible, professionally train in firearms use
Step 4: Steel your hearts and minds with the conclusion that it will be necessary to phyically harm a zombie that may have once been a person you knew
And remember to familiarize yourself with your workplace or school on all possible entry/exits and rather safe hiding places
