John Hall, my geography teacher at school inspired me to a lifelong interest in geography and a curiosity about our world which has stayed with me through my life. Geography is a living, breathing subject, constantly adapting itself to change. It is dynamic and relevant. For me geography is a great adventure with a purpose.

When in doubt, resort to animation.

I always wanted to be an explorer, but - it seemed I was doomed to be nothing more than a very silly person.

'Nice' means nothing. Is it someone who doesn't swear and shout? I swear and shout. 'Nice' sounds ineffectual.

I cut down trees, I skip and jump, I like to press wild flowers. I put on women's clothing and hang around in bars.

The trouble with travelling back later on is that you can never repeat the same experience.
