The most basic thing is to find someone to chat with when you are bored! Talk to a friend, or visit a friend's house.
There are many interesting websites on the Internet. When you are bored, you can go online to find something novel and interesting, such as "cool things, watching interesting things and playing interesting things."
Reading, of course, is reading meaningful books, going to bookstores or libraries. It can not only kill boredom, but also increase knowledge. If you are a college student and you don't like going to the library, you will lose a lot of wealth.
If you have the conditions, you can organize a real tour. If you don't, you can actually travel alone and go to the suburbs to breathe fresh air by bike. Even if you are alone, the scenery on the journey will definitely send away your boredom.
