The adventurer and author, Alastair Humphreys could have accepted the offer of a job as a Science Teacher. He enjoyed his training and was a good teacher. Alastair wrote a letter to Mr Walker thanking him for the job offer but explained he was off to cycle around the world instead. It was more of a letter to himself. A written statement of intent which lead to four years sleeping in a tent. Many adventures followed including a row across the Atlantic and walks across Iceland and India. The South Pole almost made it onto the list but the next adventure turned out to be the adventure of a family, responsibility and being needed. Alastair's travel adventures weren't over, they just became much smaller. These days Alastair designs his micro adventures for himself and others. He's looking to make them short, simple, local, cheap, fun, exciting, challenging, refreshing and rewarding. If you want to understand where Alastair's adventure philosophy is going it's worth listening all the way to the end of the episode when he plays his violin. This is his philosophy of adventure going beyond travel. Travel is what used to take him outside his comfort zone but do it as much as he did and you lose your fear because you're confident you can handle whatever travel has to throw at you. But busking in Spain without money or credit cards as backup. Sticking to his self imposed rule that he'd spend everything he'd earned before the day was out. That means waking up with no money every morning for a month. That's quite an adventure when you've been learning the violin for just 7 months and on a good day have got as far as Grade 1. Alastair is a man who understands that the ordinary needs to be balanced with the extraordinary. That fear is the adventure. He doesn't seem to think of terms of success and failure. This is a man for whom sharing his warts and all experience is what's it's all about. Now that's what I call a Teacher.
