I saw this yesterday on HBO and it was a fascinating documentary about the painter, his works, a tribute and how he thought about his own work and others. Robert De Niro Jr felt compelled to continue and try to show his fathers work because he felt it needed more eyes and to honor him at the same time.
It dealt with something important and a semi typical look into what an artist usually goes thru with their own works within his world. Often you will find an array of emotions and (personal) disappointments within an artist, it can be a thing of execution from the idea to whatever medium, self assurance or how well they've been accepted within the community of artists. We are an emotional bunch but it's because some of us have an unapologetic and harsh opinion on our own works, that will never change and it's something all artists have to cope with somehow. While maintaining sanity... well some of us do, there's a thin line of acceptance when how good you think you are and listening to others praise your work collide. Most times I value what I think over anything that is said to me because I feel that if I'm not happy with it, I won't show it and it's not good enough for me to be proud of.
Now have those inner workings of constant self debate with how the world loves the next big or hot thing. It can work itself into your mind and wreck havoc if you're not sure how to regain a level head. It doesn't matter what your working on be it a painting, drawing, photography, project, music or performance, know that you are your biggest critic and it's ok. Just remember to pat yourself in the back once in a while and recognize when you truly have something good going. You can't grow as an artist if you cannot see beyond the mud.
