Can we list useful skills for preppers to learn NOW

[Hrusai]

basic growing,
basic hunting,
basic trapping and snaring,
basic electronics,
a decent understanding of common science (i can explain most phenomena i encounter based off gcse's and half me A-levels),
high proficiency with basic maths,
proper use of a knife (sounds silly but some of the things ive seen people do )
general bushcraft skills (everything from shelter building to fire making and finding edible plants)


this will be quite a large list methinks....i think once we got a long list of items we should order them in how vital each skills is, even though it would probably depend largely on situation ....could even group items together by which of the 4 primary needs it fufills with a 5th comfort/miscellany to cover as many bases as possible
