Intelligence

I believe that intelligence is a big part of survivor, if you are just playing the game without thinking or using strategies you won't go far at all. You need to use logic and not trust everyone in your tribe or the other. Survivor is a strong physically challenging game but the contestents also need to constantly be thinking about their next move. I am not a fan of Russel but he is honestly the best at this. He is very intelligent and plays mind games with all his tribe and Galu and comes out srong in the end.
For the challenge i most likely would have went for the survival items because I think they will benefit most in the l0ong run instead of just worrying about one day at a time.
