This morning I came across this post regarding the narrative fallacy of acting like 'successful' people. It's an amusing read and some interesting perspective. At the same time, think about the Beatles, the Rolling Stones, or Led Zeppelin. Would these guys have achieved what they did if they didn't listen to American blues records? They may not have found success emulating them, but they certainly were influenced by them.
It reminds me of this element in Finding Forrester, where Jamal is having trouble finding his creative voice and is helped into the process of writing by retyping the words from one of Forrester's stories. Sometimes the rhythm and flow of playing song can take you to new places. But there I go, busting out a narrative fallacy. Anyway, the post is worth a read.
