The most precise answer I can give is that I use my love for writing to make money. It doesn't have to be one or the other. For me it's both. When I sit down at my computer I don't want to get up because I am so in love with what I do. Not only that but I feel fulfilled that the love of my life which is writing, is making me money. So for me one is not separate from the other and that is my honest answer.
I have been writing since I was a child and it was all I fantasized about doing. There is one other thing that came close to the love of writing and that is the love of cooking and I also use that to make money. It's like my work is my hobby so I am always having fun!
