Or, you could just create your own fun.
Draw, sing, dance, write a story, or create your own movie in your head. We can't wait for the excitment to come to us, we have to be a little creative and imaginative to entertain ourselves.
I think as a society and culture, we're to dependent on others to amuse us and we hear about celebrities clubbing every night and going to huge events, but the reality is, it isn't realistic to have an exciting life unless you make the little things exciting for yourself.
I can sit in front of a mirror, just making funny faces and voices and entertain myself for hours. That's mostly because I'm weird, but it's just an example.
Hope that helps. It's nice to get out of the house when you can but it's not the only way to have fun.
