Listen. Listen. Listen. If you want your character to be engaging and interesting, be engaged and interested. Be as excited to witness someone else’s spotlight as you are to get your own.
we say that to GMs all the time... if you want it to just be your story , go write a novel. Same for PCs. If you’re not there to collaborate and share the narrative, go write a novel about your character. When you’re at the table, let others shine too.
