Each of us has a mountain to climb. To reach the summit you need to understand who you are and what you can do. Without an idea of your strengths and weaknesses you cannot define your personal limits. Survival training helps you figure that bit out. It makes you stronger, more fearless and ultimatley resilient! There is no easy or pain free way to the summit – you just have to endure and climb to it by yourself.
