5. Triage ruthlessly. 有所取舍

You don't need to put an equal amount of effort into every class. Inject extra effort when it's important to you, but feel free to back off a little from classes that are a low priority based on your specific goals.

你无须对每一个课程都付出同样的努力。重要的课程可以多加把劲，但对于那些对你的目标无足轻重的课程可以松懈一点。
