I have a few of them, hope these help out:
- Dancing : Choreograph your own steps, you will feel energetic.
- Drawing/Sketching : Anything that visually pops into your head, draw/ sketch it out.
- Music composition: If you play musical instruments, you can compose your own tunes.
- Presentation/ Video making/ Film making: If you are technosavy, you can prepare your own presentations or film.
- Fashion designing : You can sketch your own set of clothes.
- Decorations:Start decorating with your own room.
- Flip book drawing : My personal favorite.
- Cooking : Believe it or not it is a form of creative expression.
- Writing: If not drawing, why don't write your story?
- Hand made gifts/cards : Prepare your own set of cards and gifts
These are the most I could think of.
Choose that way of expression that makes you happy.
