Ask like a shotgun; you are bound to hit an answer.
My friend, Eddie Rosicky (who gives and receives almost effortlessly), sent me this link around the same time that I nervously called him to ask a favor. After watching this video I realized my unpracticed way of asking for help was the cause for my nervousness.
So, cheers to the fearlessness and humility that Amanda Palmer exemplifies in this TED TALK,
and thanks to Edro for giving me an opportunity to practice the Art of Asking.
