I think Mr. Perpich mean by the best thing you have, he is trying to say is what does the best thing what Brian have? One of the two best things that Brian have is his body and brain because he is able to do a lot of other things to do with it. To know what to do and to know what is right. Brian needs to be confident and needs to be strong and healthy in the wilderness. To use his special abilities and use his strengths and his hands. And Brian needs to be responsible and complete his achievements.
