What emotions do you want the reader to feel when they are reading? Many genres are defined by how the reader is supposed to feel whilst reading it, like dramas, but most include all elements like drama and comedy. So comedy and laughter is not exactly an emotion but hopefully you know what I mean. It´s easy to create sadness, people are sad when a character they liked died. When the world is unfair. When puppies are abused ect. People get angry when there is injustice and hate. But people don´t laugh at the same thing. Some like toilet humour, others sarcasm. I don´t think I´m a very funny person in person either, I usually just end up offending people or I make a really obscure political joke and people laugh awkwardly or become seriously concerned for my mental health. So comedy, I could never write a whole book based on comedy and laughter. I do however need to learn to write a funny sentence or two otherwise people are going to end up committing suicide after reading my novel.
