Back in the day, people saw their time off as an opportunity to pursue other passions and interests. Nowadays, most people spend their free time binge watching the latest TV trends because hobbies tend to be costly, so people are less likely to invest their time or money. There are however, a number of hobbies that require very little to no cost without sacrificing fun or creativity.
First, the greatest exercise for the mind, reading. Even though most of the world is using e-books now, we found a way to read the same books for zero the cost. Simply just go back to your elementary school days and get a library card from your local library. This will then give you access to a whole collection of books for free. Then, depending on the library, you can also include listening to music and watching classic movies to your list of free hobbies because some libraries offer more than just books. Another free hobby worth investing your time in is learning a new language. With all the new technology, there are a number of resources online and in the App Store that will make learning a new language easy, fun, and free.
