I got "unintimidated by convention" from a passage in Homer and Langley, the latest novel by E.L. Doctorow. It is one of several phrases in this excellent book that spoke to me, and it was used by the narrator to describe the unorthodox lifestyle chosen by him and his brother. The book, by the way, is based on true events (with much creative embellishment by Doctorow).
I'm a pretty ordinary guy, but I've never been afraid to color outside the lines a bit. I hope to always be more concerned about whether I'm making good choices for myself and my family than whether I'm meeting societal expectations. I won't do something just because it is popular or widely recommended.* Then again, I don't usually run away from the conventional. I'm neither enamored by it, nor fearful of it--I'm unintimidated.
* Obviously, one trend I've rejected is that of titling blogs with short, catchy phrases!
