Some friends like to watch movies, every day after work to be able to have time to movie, and the ticket also like, is the biggest satisfaction in life; I like to do food, no week to invite a few friends to the house, make a big meal, try a few new dishes, I feel so good and good.
Second, keep trying. What other people think is fun, or even what you think is fun yourself, may not actually be what's really right for you.
I used to think music was very interesting, but I couldn't stick with either harmonica or piano. I still think it's great to go to the occasional musical or play though, but I can't do it on my own to evolve it into something that I can consistently have fun with in myself.
In the end, personally, I think an interesting life is based on knowing enough about yourself, and knowing enough about yourself is based on having tried enough things, so staying curious, staying healthy, and constantly experimenting is a foundation for having fun in your life, I guess.
Don't spray if you don't like it, hehehe.
