This is how I clear my mind and get inspired to go father in writing or developing a song.

I usually go off into my room close the door and listen to hip-hop and r&b instrumentals. They give inspiration to write what I'm feeling out on to paper in the form of a rap (or poetry). For example this piece I wrote last night just for fun.

Visions of my future are always never clear
But i keep a smile, my teeth shining from ear to ear
Keep my friends close and my family closer
Haters stay away or eat you up like russell stover
Gotta snap back, the mighty ducks of oregon
Ready for football season cause yes i root for dem
Dont know where i going wit this so ima have to stop
Going crazy off these meds goodbye i have to drop

It's just a fun way for me to loosen up and get inspired to write more or maybe piece together a rap. The sky is the limit.
