How Not To Prep

Too many preppers envision a single scary situation: "This is my scenario I envision."

Translation: "I literally have only one plan, and I am completely screwed if it doesn't go down exactly as my limited mind can expect."

There's wisdom in training to the most likely scenarios (natural disasters, economic collapse, etc.). But make sure you prep and train for all major eventualities. 

But too many train for the most weirdly specific situation imaginable. Don't be that guy.
