If you are just back from a visit to a fortune teller who predicted as usual good health and only the best with your love life...but when you asked about eventual success with your art she looked again at the palm of your hand and gave you your money back.
May be that's when you should consider to change something.
Recently I met an artist friend who told me being full with doubts about his works. What kind of doubts I asked him...if what I'm doing is realy art... was his answer.
I told him, you should leave it up to eventual buyers or curators to answer that question and just go on with what you are doing.
From time to time one can find some interesting 3D software that allows to take a different kind of view on your art, without spending much time on technics. This can be a nice discovery and you don't need the fortune teller to predict some pleasure playing with it.
“If you roll the dice often enough you always get the numbers you want. If I tell you the sun will shine tomorrow and that it will rain and there will be snow and that clouds will cover the sky and that wind will blow and that it will be a calm day and that thunder will deafen us, then one of those things will turn out to be true and you'll forget the rest because you want to believe that I really can tell the future.”
