Panem et circenses', or bread and shows, were everywhere and always throughout history. When people covered their primitive requirements to eat, sleep, etc they needed entertainment. That's why its industry has developed far throughout history. And now, there are a lot of ways of having fun.
But usually they are very expensive. More and more people spend most of their income on entertainment. I will tell you how to spend the least possible money to have the most fun. If you need to paint your house, for example, ask your friends if they have some paint left and if they do, invite them to a painting party. One brings tools, other brings paints, and you provide music and some food like tea and cookies. It's a very useful fun, isn't it?
If you're bored, there's nothing to do and you're lack of money, there's a perfect solution to all of your problems. Just invite your friends and organize a kind of poetry party or a video party where you will have a lot of fun reciting poems or watching videos you've just made. Play some games, and your evening won't be such a boring thing.
And how do you get your entertainment?
