Hey Shannon, It seems that you have cracked the code. Yes, I have suffered from writer's block. It is real. There have been times when I don't get the words to express my thoughts, and there are times when there are no thoughts when I sit down to write. Like you, I also jot down my research notes or reference articles/news/segments/quotes in a note-taking app (OneNote). The 21-day-habit rule didn't work for me. Frankly, I get exhausted when I write for continuous 7 days. This may be due to the fact that I am not a full-time writer (yet).
Thank you for sharing this piece. I thoroughly enjoyed reading about your experience.
