Living in constant fear and preoccupations if something bad is gonna happen doesn't make much of a life.
A car could run over you just tomorrow, so whats the point?
The forecast calls for high winds and unprecedented snowfall. It is relatively calm, with just a few flakes falling. Do you
a) ignore all warnings, and start a 5 day hike in shorts and a T shirt, carrying nothing because nothing bad could ever happen(or you are going to be hit by a car anyway)
b) Dress warmly, and carry shelter & supplies
c) Stay home with a cozy fire and some supplies
a) seems singularly foolish to me. Why do anything for future comfort or gain if you expect to be hit by a car tomorrow. This doesn't mean go live in a bunker with your dog for the next 10 years, but some forethought and planning for possible scenarios is a sound practice. Being prepared doesn't mean living in fear. Most who prepare for setbacks do so for peace of mind because they DO NOT expect to be run over by a car tomorrow.
