你只需有好玩的户外去处，再备上几件适合的衣物就行了！徒步旅行少不了合脚的登山鞋，以免脚疼起泡。如果你还打算在一趟旅行中既徒步又露营，开销或许会大一点：你得准备帐篷等设备。不过如果单单是徒步旅行，买一双好鞋绝不会超过100美元。当然，买鞋时别忘了看看能不能免费获赠远足拐杖哦！

2. Blogging

写博客

Blogging is an awesome hobby to have that might also transform into part-time income some day. All you need is a few dollars to buy your domain name and hosting. For less than $100, you can start off with a smaller site and only spend more for hosting as your site grows. Also, it’s completely free to market your blog on social media and make new friends at the same time.

写博不仅很有意思，而且说不定还能赚取业余收入呢。你只需花几块钱（不到100美元）购买域名和托管，就可以建立一个小网站，然后慢慢经营就行了。而且，在社交媒体上推广你的博客并结交新朋友是不花一分钱的。

3. Reading

阅读

Reading is such an easy (and often free!) hobby. Whether you love the newspaper or your e-reader, this is quite possibly the best hobby for improving your brain. Reading can actually be 100% free if you’re devoted to your local library.

阅读是非常容易（通常还免费）的爱好。不论是看报纸还是读电子书，都能很好地充实头脑。而且，去当地图书馆阅读可以100%免费哦！
