I have never lived as homeless on street, thus I can't emphatize enough how is it...
But if I were homeless and jobless, haven't any formal education or profession, and haven't any network (familiy or whatever) to help me in anyway, living on the street,
then I think the best asset I would have is a skill that I could use to make money from thin air.
I know it's very individual, and everyone can'y develop every skill. Some are tech savy, others have verbal skills, some are ninjas etc. (e.g. I'm a little math-guy and tech savy)
But I just want to hear (I mean read) your opinions:
What do you think is the best and most evergreen skill to learn to make money out of thin air?
I mean what skill would you like to have had to make money IF you were homeless, totally bankrupt, and living on the street?
