生存不是无所畏惧。而是做出决定，继续前进并付诸行动，因为你必须这样做。
Survival is not about being fearless. It's about making a decision, getting on and doing it, because you have to.
The mind is everything; what you think, you become.
If you don't like something, change it. If you can't change it, change your attitude.
The best way to survive in the wild is to stay calm and think clearly.
