In other words, when you bite off your own project or when you start off by looking at someone else's projects, either that we looked at last week or some of the innumerable links we included in the specs, focus on just one piece of it, get that working, and then move on to the next.
换句话来说，当你开始着手去完成一件属于你自己的工程,或者，从参阅他人现在的作品，更或者是，参考工程设计书中,提到的无数链接，至关重要的一点是，你必须让它工作，然后再继续下一环节。
