Reading
Reading is an incredibly inexpensive hobby that provides so many benefits. A single good-sized book will provide you with many hours of entertainment. Depending on the size of the book, a book will take me between two and twenty hours to read. A larger book, naturally, is at the higher end of that scale. It's something that will involve me over a period of time.
There is a nearly infinite variety of books out there, so you can surely find one or two that match your interests. There's a book out there for almost anything you can imagine. Whatever it is that you enjoy, there's a book somewhere that's going to be somewhat close to your exact interest.
Reading also improves your cultural literacy, making it easier to find shared conversation points with others. The more you read, the more ideas you have in your head and the more ways you can find to connect with the people around you.
