This is the problem right there. In my experience, successful rewrites only happen when they get done quickly. If you know exactly what you're re-writing, you can get it done within a few days. If you have no idea what you're doing and think it'll take more than a week, it will probably end in failure. The truth is, I re-write code almost every day in my programming life. I usually don't realize I'm rewriting something until after the fact.
