I'll level with you: if there is a zombie outbreak in the near future (and I hope there is), I'll probably be almost as ill-prepared to survive it as the brains-buffet shmo who squanders his time thinking about changing economic-and-actual climate. My lack of key (ha) skills in certain areas would massively hamper my looting opportunities which would in turn hamper my survival chances. Hence my desire to learn how to pick locks and hot-wire cars.
You may not feel the need for skills which would directly serve your chances of survival in post-apocalyptic contexts.* If so, which particular skills do you wish you had?
