The scene was dishonest and my heart told me it was. So, I hated everything I was writing. Once I wrote it with the correct emotion, it was fine. All of this, and many other factors that cause bad writing make us afraid to sit down at the keyboard. Writing then becomes a sporadic endeavor.
Fear of failure leads to a lack of effort.
Trust me, it's okay to write garbage. You can learn from bad writing. Don't try to be brilliant. It's not that hard. Make up a good story, then let it flow.
