Don't listen to the people who tell you, "you can't do this or that.."
They only say that becuase they failed to accomplish it themselves.
You want to know if you can make a living as an artist?
I know artist who make $100k-$300k a yr. There are LIVING artists who sell millions of dollars worth of their own work. So, yeah..I'd say you can make a living.
If you go through life settling or choosing to avoid risks will only lead you to failure and mediocracy.
You only truly fail when you quit.
I know you are scared.
But don't avoid fear. Follow it.
"If one advances confidently in the direction of
his dreams, and endeavors to live the life he
has imagined, he will meet with a success
unexpected in common hours."
- H.D. Thoreau
