Is this a Writer's Block or just Pressure Building?
The more I try to write something "good" the less I can write anything at all. The pressure to write in order to reach some level of "good writing" blocks my brain.
I am sure many writers go throughout the same phase.
What can we do to get out of that block?
Write nonsense. Write how the character is frying eggs in the morning; write in a ridiculous font; write something silly that will make you laugh or roll your eyes; write a parody of your own work. Just write!
Stop taking yourself all that serious.
Embrace the embarrassing mess of your first draft.
It will get better afterwards. Just write the needed nonsense that will help you focus, that will make you feel the joy of writing, in stead of terror of not being good enough.
Thus, gradually, as Simon is frying eggs in the morning, he comes to think of that girl he likes. He spaces out as he remembers the sound of her voice sounds as she calls his name.
The eggs are burning, but Simon doesn't notice. He is going to get severely burnt. I need to go to help Simon, I need to go start writing.
I hope you get to do some writing today, too. Help your characters cook breakfast. That's a start. Write, just write, and then keep writing...
