Okay, so I just had to ask this, but I'm attempting to write a book, and so far I don't have much down yet, though I have pages after pages of scene ideas and plot details and all that. But the only thing is, what I plan to write is constantly changing. Main story wise it doesn't change, but most of whats held within. Like for example the characters, from time to time I start to fall in love with this new character I'm crafting, and wish I could give them a bigger role, so I replace one of the main characters with them. But it's not like I'm replacing well thought out developed characters, what leads me to being okay with replacing them is I realize I have no real idea how to right said character, I don't really know what to do with them despite thinking I did in the beginning, and this new one, I have a more solid idea, and I add in traits from the dropped character to fill them out. But not often, but once or twice thus far, I've done the same thing to that one when I create a better one I feel will work better in the story. And plot wise I keep changing certain details, like how things start, the various details of the world it's set in. But anyway, what I'm asking is, is it bad that I'm constantly changing things like this?
