I totally feel you! I just try to contribute a bit every so often. I find that it's so easy to come up with ideas, but they get lost on the way to getting put into words if that makes any sense at all. Idk. I just write if I feel like it when I have free time (which isn't much lol). I find that I am most productive with my writing at school between my classes. So I update like once every month or two? Idk. Just have fun with it and don't put a bunch of pressure on yourself to get it done.
