Maybe try drawing something you have always wanted to? or try something completely different! a new style perhaps? or do work for someone else?

They say the best way to get new idea is to go out and walk around ( or just change your surrounding ) but I know what you mean about real world taking over. When I was doing my co-op ( first real work ) By the time I got home I had 0 energy for art, just played EVE all night :/
