My takeaways from most survival stories and advice are: be flexible and improvise. (I am thinking wilderness survival / stuck in car survival / etc)
I'm concerned that relying too heavily on a big pile of precisely the right emergency gear may give a false sense of security and lead to inflexible thinking and panic.
In real life nothing goes as planned. When (not if) some of that gear you're counting on is lost or damaged, it may be all too easy to despair and get focused on what you don't have instead of what you do have (or can find).
How do you address that when putting together an emergency kit? Or when practicing survival skills? How do you make sure you always have the kit when you're likely to need it?
Do you figure out a way to disperse the necessary items across your pockets rather than carrying a single container kit (all eggs in one basket)?
Do I include gear with overlapping functions? E.g. fishing line + 550 paracord + snare wire? Or e.g., lighter, matches, flint/magnesium?
Do you rate stuff according to utility or previous experience? And include only the highest rated?
