Usually my door's locked, and I live in a rural area. There's a window by my bed, so if the zombies hadn't already gotten to me, I would survive by doing the following:
1. Get comfortable, low drag clothes.
2. Grab pellet guns.
3. Arm self with wooden sword.
4. Grab Legend of Zelda sling bag.
5. Pack with water (in a container).
6. Bring phone in case I'm near an area of rescue.
7. Strap knives to side in a fashion where they won't cut me.
8. Find straw stash, gut, then fill with pellets for speed loading.
9. Put cloth in bag in case of bleeding.
10. Put pocket knife in back pocket.
11. Run outside in search of survivors.
12. If no one present, head for mountain base (1 mile away).
Because I have very low stamina for a skinny guy, I can't run far, but I can sure run very fast.
13. Fight zombies.
14. Enter convenient store, grab all water and snacks.
15. Leave, fight zombies.
16. Run up mountain, heading toward the mountain house near the peak.
17. Fight more zombs.
18. Make base, barracade walls.
Worst case scenario, I run out of snacks, go to get more, and get overrun.
