I used to face that urge of painting over frustrating works. Now I stay with the works and see them through. I have a bit more patience now. I guess I now know how to better resolve painting issues. Indeed, having access to our older works can motivate us to push on through.

"Everybody is an artist", "Everything is art", not true, because as you rightly said, it takes, sacrifice, passion and importantly commitment. Not everybody has that.
