Right now I don't feel like I have an passions. In the past I have had several so I will relate three of those.
1. Piano. There is something about playing the piano. You can express happiness, despair, love, hate, energy, or even lethargy all with the same instrument. I can get lost in the music as I play, and I can put sound to my feelings.
2. Dance. I didn't get to do as much formal dance training as I would have liked, but I did pick it back up in college and take dance almost every semester. Dance is like piano, but instead of sound, it is with movement. You can also express, and even feel someone else's emotion with both, which is beautiful.
3. Books. See post about dream job.
At school Ella's class made personality maps (or something like that). They wrote their names in the middle and then surrounded it with things that made up their personality, likes, or feelings. I loved Ella's and was so glad she thought of so many things that make her who she is!
