Revising My Story Plot

My world building and general story plot needs work, so the last few days have been devoted to that. It is a bitter pill to swallow when it is pointed out to you that your characters aren't likable. I want to be a better writer so having it  pointed out when I am only a few chapters in as opposed to halfway through the book. So this weekend will be devoted to rewriting the first four chapters and getting them out to my critique partners so that they will be able to follow the new direction that my story is about to take.
