I've always been an inspiration-driven writer too, but what inspired me never turned out to be something other people liked. I suppose if one is going to be a pro writer one has to look at writing more as a craft than as an art, more as work than play. But I'm only saying this as someone incapable of doing that, so I have no solution. Perhaps there are rare occasions when art and craft, work and play merge. If so, I'm still waiting for the lightning to strike...
