A individual can have all the knowlegde in the world on the topic of survival.

If said individual doesn't have the proper mind set of I can and Will survive.All that knowlegde is no good for him/her.

If ever placed in a survival situation.Convince yourself I can and Will survive.

If it takes the individual to stop every 5 minutes to convince him/her self.

Saying out load if permisible. I can and Will survive.Then so be it.

Over time the lenght between stopping and convincing ones self, I can and Will survive.
Will increase until survial becomes, [it ain't nothing but a thing], just like breathing.

Ask anybody that is forced to live on the streets or in the woods.
