Quite a longtime ago, when I was slowly getting into music, I made quite a weird little song called "No Sun". It wasn't very good, but it had a nice main melody. Years later I took that melody and built a brand new track around it. I like how it points to a fact, that eventhough we all evolve, we all keep redefining ourselves over an over, there's some core values in us that, if we get lucky, never change.
