If I spent my time and focused on another mans business where would I be ???
Keep your head down , move mean and never look back . You might end up somewhere you never imagined
If you're waiting and hoping that someone will buy your art. THEY WON'T. Everyone who follows you has passed or doesn't have the money.
Go make new connections, make new friends, promote yourself creatively. Put as much work as you did into your art, to helping people find it.
