This will not be a real text but a bazar of things to survive I discovered during my mutation, from a nice hot-line worker in a music company to an urban camper (tent, mobile speaker and machines, etc)

Take with you lot of things you can find on the streets: carton (bed, fire), strings (to make candles, paking)

Always ask food shops if they got something for you on evenings, search trashes of supermarkets too (see freegan.info)

Go in the churches to see if they have bad candles they can give too you, then you can make new with it by destroying them in a thunfish can and putting a string in the middle (during winter, 3 candles warm a good tent, the thunfish candles can't fall and burn your bed in the night)
