I spend a lot of time developing characters, but there is a risk. We want something to happen (I think). There has to be action. But we also need characters we care about (at least I do). But taking page after page to develop characters seems to slow everything down. Chapters of character development are ones I revise carefully and often delete. Things that interest me about a character (I tend to really love my main characters) are probably less interesting to my readers. So - care, balance, careful writing. Work. But I think it is necessary work. Characters are crucial.
