Let's face it–even under the best of circumstances, project management is hard. There are so many facets and factors to consider at each project stage, including several that will change (sometimes dramatically) over the course of your project.

And that's just to name a few; there are many more insidious things that could cause problems that could delay or even derail your project completely.
