It's hard to pinpoint Dave Cornthwaite's actual career, he is a man who does a little bit of everything. He is an author, an adventurer, a public speaker, but most importantly, he is doer. He is a yes man, and he lives by the philosophy that everyone should say yes more often. Dave has created a Yes Tribe in hopes of motivating others to be more active. Dave is currently undertaking Expedition1000, a 12 year plan to undertake 25 one thousand mile journeys using non-motorized transportation. www.davecornthwaite.com, www.anygivenrunway.com
