So I have many talents, such as acting, writing, playing instruments, singing, and drawing. Will colleges like this?
Yes, put it all down on your application.
All excellent ECs.
If you can show that you have used and developed those talents, then colleges will like that. If you have performed, published, or exhibited, colleges will like that.
If you have a drawerful of unpublished manuscripts and art and the only people who have heard you sing are your parents, then colleges won’t really care. They like to see development and progression.
