I used to write when I was in the mood or felt inspired. Anymore, I write whether I feel inspired or not. It's a discipline. So that's definitely different. It's part of maturing as a person and as a professional.
I fell in love with books. Some people find beauty in music, some in painting, some in landscape, but I find it in words. By beauty, I mean the feeling you have suddenly glimpsed another world, or looked into a portal that reveals a kind of magic or romance out of which the world has been constructed, a feeling there is something more than the mundane, and a reason for our plodding.
