Ira Glass on Storytelling

Lately, there's been much discussion (amongst my friends and I) around "creative drive" - that inherent awareness that we are still unsatisfied and looking to push our work further...where does our tenacity come from? Ira Glass points out that the gap between ability and taste, is what drives creative people to achieve great things. So weird...I've never thought of it as a gap...when I think of it now, it's kinda like "duh!"
