I constantly have new hobbies because I love to try new things and I need to be busy to be sane. I can't stand just sitting in front of the computer or TV all day. :P
Anyway my hobbies include:
1) Writing (including songs, poems, movies, TV shows, short stories, articles, novels, plays, one-shots, and more)
2) Reading
3) Listening to music
4) Playing the piano
6) Inventing languages
7) Making collages
8) Designing outfits
9) Creating my own fantastical creatures
10) Collecting things (they alternate--so far I have collected erasers, stickers, stuffed animals, books cat-related things, and mannequins. I am now collecting horse-related stuff.)
11) Acting (I plan on taking a drama class at school next year)
12) Doing volunteer work (I am going to join Y-Teens when school starts)
13) Protecting the environment (I am going to join the school Green Club)
14) Photography (I love to take photos and edit them. I'm going to join the school yearbook club)
I think my next hobbies are going to be sculpting, role-playing, and sewing.
Oh, how I love hobbies!
