Food for thought: I would say that at the end of the day, editing is the most painful for new filmmakers. Why? When you sit down to edit, you can see and hear everything that went wrong on the shoot....poorly recorded audio, poor camera white balance, out-of-focus shots, no cutaways, continuity issues, things in the frame that are not supposed to be there (like a light stand), missing shots, etc. Moral of the story: try to surround yourself with talented people. They can prevent a lot of problems from happening.
