So true about some successful performers. (LOVE Robert Palmer, BTW!) A lot of entertainment types reach a certain level of success and then feel the need to step out of the box whether it's music or politics. Success in one area doesn't guarantee success in another, or make one an authority on every subject. But it certainly seems to be a common occurrence among the successful, unfortunately. I can't find the quote but I think the "famous sonwriter" I'm quoting is Jimmy Webb ("Tunesmith"...the book) and "By The Time I Get to Phoenix", etc. And I'm not sure at what point in his career that statement was made. But there are a number of interpretations of the quote. Basically I think it means to not be afraid to fail or appear foolish when you sit down to write. Don't try to make ever word and every line the beginning of some mega hit. Just get out of your own head and let the ideas flow freely...i.e..."spitballing". And whatever you do, don't actually throw away anything! I have briefcases full of songs and snippets written over the last 35 years, and l love going back and reading what I wrote. Some of it I can't believe came from me. And I try to remember my inspiration for the words. More importantly, years later I've found new inspiration in some old lines and proceeded to turn them into a new song. Anyway..."writing for the trashcan" is, of course, not a literal statement, but rather an encouragement to free ones mind of any mental road blocks or hindrances before setting about to create. What an incredible creative process to be a part of, isn't it?
