Don't expect to understand things, much less remember them, the first time you study them. Trust that things will get clearer as your brain comes to grips with new information. It is like a jig-saw puzzle or a cross-word puzzle. As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but on its own schedule. Learning does not take place according to a schedule laid down by a curriculum or teacher. Some things are easier to learn than others. Some things just take longer to click in. Keep at it, and you will gradually find that things that seem difficult at first, will become second nature with time.

当一开始学习的时候，别指望能一下就全部理解、更别说记住所有知识点了。要相信，随着你了解越来越多的新知识、你的头脑也会变得清晰起来。这就像是拼图、或者填字游戏那样：当你把图形一个一个拼起来、或是把单词一一填进去，整个大局就会清楚。大脑其实随时都在学习，不过它也有自己的节奏。学习的过程是不会按照一个课程、或是老师给你规定的进行的。有的东西比其他好学，有的东西就是需要花更多时间。坚持下去，你慢慢就会发现那些一开始看上去很难的东西也会随着时间变得简单了。
