Wow, I've got nothing, I'm not good at any of that stuff.
If I had to give me anything I would say Endurance, because I seem to be pretty good at taking physical pain and I can also go for a week without food and sleep, sure I was not really fine when that happened but I'm fairly sure not everyone can keep walking when they are really tired, hungry and having hallucinations, I don't put this on survival though because I didn't do anything that would help me survive, I just kept walking and walking, no looking for food or building a shelter.
Other than that I guess maybe luck because well I somehow get out of trouble even when it really seems like I'm screwed, and since I don't really have anything else going for me, maybe Will/Spirit because well I don't give up and just keep going, if I had another thing maybe a little charisma from my good looks but that doesn't help that much when you are horrible at talking.
