I like both points of view here.

Jot down and notate lots of ideas, as they arise, and file them.

Then, of those ideas, one or two will emerge which have promise.

Then, the hard work begins, in shaping an idea into a finished piece. Maybe combine bts and pieces from more than one train of thought ? Whatever the process, it;s those small little hooks or grabs, which wiil prompt more work on a song, until hopefully, one day, you're happy with it. Not ! LOL

Write on.
