Thinking Of A Master Plan

Ive been thinking of what my project can be based on and ive narrowed it down MUSIC....the only question is what the heck can i do with music. And ive have no answer yet. I know there is a large amout of creativity awaiting my appearance......with music. I just have no idea what i should do, i think i might work on music in different languages i know songa in Japanese, korean, and spanish, but one of my goals is to relate this with a original composition, i sont know what to research or what to base off of. Music is the center of my life but it branches out to like everything.........I need to narrow this a bit.
