Writing sucks. I think it's terrible. Writing is not fun, and don't trust anyone who claims to enjoy it. Liars!
Writing in a lot of ways feels more like excavation than construction. It feels like you're uncovering this thing bit by bit, discovering what it is, instead of constructing it upwards.
If I spend a year and a half writing a script, the first year will be outlining in notebooks. It's just the way I work, definitely not necessarily the best way.
When you're writing is when the "god should I just drop this" feeling can hit. When you're editing is when the "god this is awful and I've wasted everyone's time and money and will be revealed as a fraud" feeling can hit.
You go from these high hopes when you're writing to just a desperate want of not making a complete fool of yourself by the end of it.
The momentum of production keeps you from giving up, so it's really the editing and writing phases where things can look bleakest.
Rather than thinking in terms of a specific genre or specific kind of thing, I hope I can just stay relatively small and keep making my movies. If I can keep writing them and making them, I'll be happy.
