Oh boy.. Well.. Minus the obvious food, water, friends, family, etc..
I require quiet a few things to actually keep me sane.
A computer, but not just 'A' computer, MY computer.
My computer includes:
Music, Ipod, Arduino, Internet, Online Games, Coding, and everything else you do on the computer.
As long as it's my computer I have in my possession I should be good.
Mainly because I have everything I need on my computer =P
Now if I could overclock my CPU to cook on I would be all good!
