More often than laziness, the root of procrastination is the fear of not doing a good job.
The only way to overcome procrastination is to abandon perfectionism and not fuss over details as you move forward. Pretending the task doesn't matter and that it's OK to mess up could help you get started faster.
Many ambitious and organized people try to maximize their productivity by meticulously planning out every hour of their day. Unfortunately, things don't always go as planned, and a sick child or unexpected assignment can throw a wrench into a person's entire day.
Instead, you might want to try planning just four or five hours of real work each day. That way, you can be flexible later on.
