After earning my daily bread as a writer for 30+ years, I can honestly say I have never had writer's block. If I start it, I finish it or I trash it because it can't go where I want it to go. Besides, If you write for a living, there is no time for writer's block. Essentially, you've got the "write" idea in your final paragraph.
30+ years, very impressive... I feel like a child next to that number...
Just remember, a person can make the same mistakes for years and call it "experience." Hopefully, I've gotten past that. ;-)
