Threat plan.

Ask yourself the following:

What do you have that you want to protect?

Can be a person, place, thing, animal, mineral or vegetable.

A hierarchy of importance is good to develop.

    Is your wife more important than your cat? 

    Is your fireproof safe full of legal documents more important than your computer?

Who do you want to protect it from?

Threats 

    Consider:

        Actions taken by humans

        Acts of nature (acts of your god?)

        The passage of time

How likely is it that you will need to protect it?

Remember:

    Privacy is important

    Everything breaks down eventually, both man and machine, society and civilization

        Will a hurricane demolish your mountaintop resort? 

        Will a landslide destroy your yatch? 

        Will looters ransack your home during an insurrection?

    Historical weather and earthquake data is useful to know

How bad are the consequences if you fail?

What do you have to lose beyond possessions and people?

    Reputation, freedoms, integrity, etc.

How much trouble am you willing to go through to prevent these consequences?

Will you go through worse if you don't prepare?

Will you have the courage to act when the time comes?

How many security cameras are needed to track a single cat? What about a married cat?

After you feel you have answered these sufficiently, you can begin to prepare to protect yourself!
