To the many people who have trouble completing the last step of a project, Seth Godin has some advice: Ship often. Ship lousy stuff, but ship. Ship constantly. At the end of our parasha, the Malbimmakes a similar point. The Torah tells us: And Moshe completed the task. The hard part of the Mishkan was declaring it to be ready and complete. Only Moshe had the courage to do this and so although many others were involved with building it, he's credited with completing it – he declared that it was it ready.
