Finding motivation after beta readers

Guys I just needed to share. I have received the feedback from my beta readers, for my upcoming horror novel, and one of the major things they pointed out is that my characters are lacking somewhat of motivation for them to really get to the major horror turning point.

While at the start I was a bit upset because I thought that wouldn't be a problem, I finally got some time to sit down and edit based on the feedback, and oh boy! I found my motivation to write again!

By focusing on perfecting that specific aspect first, I am managing to make my characters much more real and intriguing, and their relationships are getting more complex, which is something I needed as it is hugely a psychological horror novel.

We see so many negative posts about things that don't work here that I decided to share this good thing that happened to me, and now I ask of you:

What are positive things that happened to your story after you've received feedback on it?
