Preparedness gives me a satisfying sense of control of my fate.

I exercise power over my circumstances by turning "big" problems (view of others) into "little" ones (for me) by thinking ahead and taking some actions to mitigate the extent of the problem.

Lots of great hobbies can result from further exploration of the possibilities. Knives lead to knife-sharpening. Shooting leads to reloading and accuracy. Hiking leads to knowlege of energy/water/heat conservation. Camping leads to reduced fear of power outages. Etc.
Wife's deep interest in sewing leads to stockpile of barter sewing machines & fabrics plus ability to repair or make needed clothing.
Desire for situational awareness can lead to radio hobbies (ham radio, scanning).

Preparedness starts with knowlege and knowlege is power. And as we all know, the more power you have, the more you want :-)
