Indeed making music is hard, especially as a solo artist. Songs come about in different ways to me. Sometimes I'm improvising on the guitar and hit a tune that I feel I could expand on and go from there. Sometimes I just suddenly come up with a tune in my head. Sometimes lyrics pop into my head first and have to come up with the tune later. Any way that I write a song it all ends up in my head. Then I am faced with the daunting task of learning it. Sometimes I succeed in matching the vision in my head, other times I stray from the original vision completely. Either way a song is born out of it. Then comes the task of recording and editing, in which, often new ideas are born. All this combined makes it hard to ever consider a song complete. It seems there is always something to add, take away or rearrange.
