To write a novel and keep going, you need to be passionate about your story. Find inspiration from various sources and don't be afraid to take breaks when needed. Another tip is to have a support system, like fellow writers who can encourage you.
One way to make a story last longer is to develop the characters more deeply. Give them complex backstories and evolving motivations. Also, introduce subplots that interconnect with the main storyline to add depth and breadth.
It could be a book club. Book clubs often look for novels that are interesting to discuss. If the 'you novel' has multiple layers of meaning, different interpretations, and strong themes, a book club would be likely to love it. They would have great discussions about the characters, the plot, and the overall message of the novel.
Set small goals for yourself and celebrate when you achieve them. Also, take breaks when needed to avoid burnout. Sometimes, sharing your progress with others can give you the motivation to continue.
The 'what the hell' feeling might come from a combination of factors. Maybe the pacing is off, the rules of the ghost world are unclear, or there are sudden plot twists that catch you off guard.
