Take for instance this:
(Okay, this movie was fun to watch, but HISHE makes a good point.)
(That's so awesome) When someone reads your work and they say, "Why didn't (insert name here) just do (insert action here)?"
That's when a writer usually says, "You just don't get it," while shaking head... "I'm a writer, this story can be anyway I want." (No...*uneasy look* I don't know that from experience. *nervous laughing*)
Okay, this is a big mistake (see video above for reference). When someone says a part of your plot won't work, believe them, revise, and move on. Because you want your book to be better.
Have a great week writing everyone! I have to go change that one scene on my book...you know...the one that I thought was cool, but ...my character can't conveniently fly...but it would be cool! Have you ever had to change your plot because something just wasn't working?
