You're not human if you don't feel fear. But I've learnt to treat fear as an emotion that sharpens me. It's there to give me that edge for what I have to do.

Why is it that the finish line always tends to appear just after the point at which we most want to give up? is it the universe's way of reserving the best for those who can give the most? What I do know, from nature, is that the dawn only appears after the darkest hour.

A wise man knows; learn from others, never get complacent and know where the classic old dangers come from.

Survival can be summed up in three words - never give up. That's the heart of it really. Just keep trying.

The rewards of the wild and the rewards of the survivor go to those who can dig deep, and, ultimately, to the guy who can stay alive.

The rules of survival never change, whether you're in a desert or in an arena.

I do see a lot of the hard end of ecology, and my feeling is that we live on a super-exciting planet but a super-fragile one.
