A lot of great items here, but number one resonates the most. One of the most common problems I've seen on any project I've ever worked on (my own side-projects included) is a difficulty in saying 'No' to things. The list itself would benefit from the same advice -- cutting it down to half as many items would have upped the overall quality IMO.
