Step One

The first thing you do when you know this is the apocalypse is for you to go home. Doesn't matter where you are, school, work, the gym, or at the mall (especially if you're at the mall), you go home ASAP. You need to regroup with your family. Not all of them, just family you live with or live close to you. Once all your family members meet back at home, grab the phone and start making some calls. One person calls family, and another calls friends. The person calling family asks how the outbreak is happening in their area, telling them to stay put and you will all meet up together later. The person calling friends, is only calling close friends. Friends you want in your survival group, people you can trust. People who won't abandon you during a zombie attack. But not many; 2-3 people maximum. The more people, the more different opinions, the more arguments, the more mouths to feed, the more fuel burnt traveling on the road, etc.  BUT you will need several hands to hold down a fort, so don't be completely alone.
