If I take this article a bit more literally - I was afraid of flying too (with airplanes), then I decided to put an end to it and took skydiving lessons; Yeah the ones where not only you climb to the sky with a plane, but you jump out of it on about 13k feet (4km). Liberating is pretty much the word that describes it, and I'd also like to think about the same sensation (minus a bit of adrenaline) when you actually succeed (however you define success is up to you) in business.
