That is how I learn. I have nothing to lose by trying. I have everything to lose if I don't try and keep experimenting. Embarrassing creations are part of the learning process and they are good and not a waste of time. The reality is that I often have no idea if what I am doing is good while I am making it. If I'm lucky I will know when I am done, but often I am unsure. But that the fear is actually a good sign that I am onto something and not playing it safe anymore. Being an artist is rarely comfortable. Be wary of comfort as an artist. I ripped up an old collage that I did not like and salvaged the board to experiment with this portrait of my daughters. I may eventually do the same with this but for now I am happy that I tried something.
