Right now it's this tune by Hatebreed.
In particular the lyrics of this verse and chorus echo my determination to get better with my art.
If you want to make a difference in the world it means
You have to be different from the world you see
No victim mindset, raise your standard
Your true self calls and you must answer
Lift the weight of the false self crushing you
Lift yourself up from malevolence
Lift the curse of the fatalist haunting you
Lift yourself out from the death grip
Lift the burden upon your shoulders
