No, but I've been working as a screenwriter for more than 10 years now.
I co-wrote two films, both did well on the festival circuit, winning some awards and received glowing reviews, but they were both commercially disappointments. The TV-shows I've worked on were the other way around: negative reviews but viewers liked them. Currently I'm the head writer of a telenovelle, which is fun to do, but also very time consuming, since we have 4 episodes per week.
