Surviving in the wild, could you do it?

[activedenial]

i have been schooled in the art of survival.
i have been broken and remade.
i can hang.i have been tested.
i have spent four long days and nights
all alone with a ziploc of rice an onion and a carrot
four bouillon cubes and a canteen.
the earth will provide.

I have never gone alone but want to try it. i have only gone with freinds so far, but I want the challenge going alone. How was it at night? I fear bears the most, just because I have seen them already in the wild. I know that even with a gun it might not stop them from jumping ontop of you when your sleeping.
