If you don't know how to make a bow drill or hand drill, how to gather/keep tinder, how to find water, how to make weapons, how to hunt/trap, how to build shelter, what plants are edible/poison, etc, then you are NOT prepared.
Only those who have learned these special skills are truly prepared.
If you desire to do so, then I'd suggest reading and practicing those skills found in the book "Outdoor Survival Skills" by Larry Dean Olen, no finer text exists on the subject.
There is a course based on Larry's work offered at Boulder Outdoor Survival School (BOSS). link here:

There's also useful information on the web:

Unless one practices these skills, your chance of survival after a major disaster (the kind likely to happen in the near future) is dim.
BA- Nothing like a dose of reality.
