So a use case is a text description of how you want the system to work, who's involved and how they interact, how it all works when things go right, and what should happen when things go wrong.

In fact, the worst case scenario is that things don't work out and you have to go back to doing exactly what you are doing right now.

事实上，最坏的结果也只是你没有实现梦想，然后只能回来接着做你现在正在做的事，如此而已。
