When writing do you know your protagonist really well? My first few books have not been great because the main characters weren’t properly drawn. I just written an other one but before I started a write a character bible and practiced putting the. Into all sorts of situations, most,y not related to the book plot, just to make sure I could write them. Sending them on dates, to the theatre, walking in the wild and eating dinner at home with family. None of which is relevant. Now I feel I know them that writing them is easier and more natural. Is this a technique that anyone else uses.
