Learning is a lifelong process. We are fortunate to have all these resources and opportunities online. Don’t waste them; make the best use of them instead.
学习是一辈子的事业。我们很幸运地能在网络上获取各种资源和机会，应该好好利用它们，千万不要浪费了!

1. Read selectively on a wide range of subjects
有选择性的广泛阅读

The first level deals with the widest range of subjects. Here you need to follow many different fields so that you know what’s going on out there. To do that without consuming too much time, you need to be selective in what you read.The nice thing about this method is that even just reading the titles can give you some understanding of what’s going on in a field.
首先，我们需要涉猎广泛。你需要看很多不同领域的文章，这样才会知道世界发生了什么。但是为了在泛读的时候不花太多时间，你需要有选择性的阅读。这个方法的好处是，你只看标题就能大致了解某个领域发生的事。

2. Dig deeper into promising subjects
深入了解有前途的领域

By doing the first step, you will notice a few things that seem promising. They could be an emerging trend, a new tool, a new market, or whatever it is that can take your work or life to the next level.
完成第一步后，你会发现有些事情看起来很有前途。有可能是新潮流、新工具、新市场，无论是什么，这些事物都是能够使你的工作和生活上升到一个新的层次。

When you find such a thing, you may want to spend more time to learn about it. Here are a two things that you can do:watch the YouTube videos and read people’s opinions at social media sites.
当你找到这样的事物后，你会想花更多的时间了解它。可以试试以下两件事来帮助你了解：看视频网站上的相关视频，或在社交网站上看网友的评论。

3. Take an online course
参加网络课程

When I got interested in iOS app business, this is what I did. I took an online course on iOS app development. I watched all the videos and did all the exercises. Taking an online course takes a lot of time though, so you should do this only for a few selected subjects.
当我对苹果的应用商店感兴趣时，我通过网络课程的学习来了解。我报名参加了苹果应用发展的课程，而且把所有需要看的视频和作业都完成了。网络课程会占用你不少时间，所以还是精选几门课程参与为宜（去沪江网校听免费公开课吧>>）。

4. Create a real-world project
通过具体项目实践

This is the deepest level and, in my opinion, a necessary step to really master something. Taking a course is good, but nothing can substitute the learning experiences you will get from being in the real world.So, if you want to master something, create something real.
这是最锻炼人的一步，而且我觉得只有这样你才能真正掌握所学。虽然参与课程也能掌握知识，但是从实践中掌握的经验是无可替代的。因此，如果你想学什么的话，必须最终应用到实践中才行。
