I think Perpich means that if you don’t know how to use the things you have then those things are useless. So you have to use your brain to get motivated and creative, use your body to get active and start trying. Brian has to try to survive and this helps him to think positively. That’s how Perpich helps him. If it wasn’t for Perpich Brian could have just thought negatively and could have just sat there and cried. He also might have been too scared to drink the water because the water was to dirty and would have died earlier. Even though Brian was scared, he still fought through the fear and drank the water. I think Brian is very brave and confident to try to keep going. He is fighting his difficulties. Brian might not. I have any food but he’s still determined to survive. The positive thinking was the key of Brian’s determination, bravery and confidence. I think Brian thinking positively is giving him a reason to survive and that if he survives this tragedy there will be an award waiting for him.
