Eloen Well, I understand your point. I had faced it once too. It was long ago when I was just a regular reader here. I wanted to write a story for a long time but just never had an idea that wanted me to start writing. Then, a bug from WN helped me. I remember it being the translated webnovel "When a Mage Revolts". I had commented on the last chapter of the book with, "Shit, it ended!". The funny thing that happened next was...below my username, the label of author was posted. it was a bug and was rectified within 45 minutes, but that feeling was different. and, before I knew it, a story had formed in my mind.
I then began to write it ina notebook, just like a draft, filled with messy scribbles. i added ideas, sentences, characters, etc. everything I could think of into it. then, I began to write the first chapter in it. it was a really awesome experience. it took me a lot of hesitation to start the first word, but after that, words and sentences automatically poured out. all I just needed to do was to move my pen.
before I knew it, I had written my first chapter. i continued at the pace, taking my sweet time to write it. at the end of the week, I published it here. since it was my first novel, I had made plenty of mistakes in it. but still, facing all the criticism I received, I tried to improve my skills.
Stamping the first word is the most important step. The rest will follow suit
