A mistake that budding creatives often make in their youth is to throw away their early artistic attempts out of insecurity/misplaced perfectionism. But what an inexperienced artist lacks in technical ability is often made up for with inspiration.
When I dig out a piece of music I recorded at the age of 17 and develop it further I see it as a collaboration between the experience of my older self and the inspiration of my younger self.
DO NOT THROW AWAY YOUR UNFULFILLED PROJECTS!
There's gold and magic in them.
