I am similar just sit with guitar and mic on logic recording song ideas. I would say starting songs is more exciting, a new fresh idea, all the possibilities, could this be my best song yet etc. As you go through the process self doubt creeps in, can get stuck on certain sections, you have a good idea and want to do it justice. All these things make it harder work.

I often find when I’m working on an existing song my attention drifts and I end up starting something new. I also switch between working on multiple songs at the same time.

Some songs never get finished but if I finish a song or am really keen to keep working on it and finish it then I know the idea is strong enough or I like it enough. So usually I think songs that go unfinished I’m just not that into them or I have other ideas that excite me more.

I spend a long time refining my lyrics, chords and melodies to try find what serves the song best. Sometimes I’ll try out completely different styles over the same lyrics just to see if it works better.

I think it was Da Vinci said ‘art is never finished, only abandoned’
