So I started loosely outlining the 'first' book. I had an awesome idea and wrote the beginning, now expanding and planning out what events will take place. While halfway through doing that I had what I like to think was another awesome idea for a sequel to the 'first' book. Is it ill advised or bad luck to outline or plan a sequel before you've actually written the first? I tend to have an issue with pacing myself by getting too excited for all the ideas I have, so my loose outlining was intended to help me pace. Apparently it is somewhat working cause I have been able to plan ahead. Should I try to loosely outline the 'second' book as well, or just write down the essential ideas then refocus on the 'first'? I know characters change a lot even from what we think, so do not want to restrict anything! What would you do? Thank you!
