I agree - writing is mostly a lottery... anyone not doing it because they love it is going to be sadly disappointed! I think something similar happened with - going to get the name wrong now - was it 'Diary of an Edwardian Country Lady'? That was 99% luck, and somebody bored out of their skulls reading it in their lunch hour. Helluva a way to make a living!

I guess your best bet is to get an agent? Bet that's a lottery in itself. I'll keep hoping for the day you tell us you're going to be published... and send you bucket-loads of persistence and tenacity to help keep you going :~D
