I think one of the most important things that I learned about watercolors was not to give up. (I'm not saying I never give up but usually I try to see the painting to it's finish.) I used to give up on a painting when I wasn't happy with were it was going. then an instructor of mine said to keep on going. I didn't learn to do this overnight but eventually I did. I must say that I have learned more about watercolors by not giving up but working through my frustrations. Not every painting comes out great but sometimes I'm really surprised.
