Survival can be summed up in three words - never give up. That's the heart of it really. Just keep trying.
There's no magic to running far or climbing Everest. Endurance is mental strength. It's all about heart.
Survival requires us to leave our prejudices at home. It's about doing whatever it takes - and ultimately those with the biggest heart will win.
Accidents on big mountains happen when people's ambitions cloud their good judgment. Good climbing is about climbing with heart and with instinct, not ambition and pride.
And if you give your heart to a goal, it will repay you. It's the law of the universe.
And Jesus, the heart of the Christian faith is the wildest, most radical guy you'd ever come across.
It breaks my heart that my father never knew my children. He should have been around for another 25 years.
