Chip away at the right place.

Something really big and important can seldom be completed in one pass. Being big and all, the task often contains interlinked parts, some of which are more important than others. Even amongst the important parts, some more accessible than others. Begin and continue working at the places which will have a positive and increasing impact on the overall project - the parts that are crucial to the whole. It can be dressed up later once the core is in place.
