I 100 % agree with you! Reading your post I can say I have the same thought of you. Me and my hubby are both artist, so you can understand how difficult could be to find the right "equilibrium" between our creative work and the money we need to live (and to buy tools and colors for our works too ^_^). As you wrote, in every creative work an "adequate time for reflection, experimentation and to make changes" can take few or a lot of time, simply it's done when it's done. It's not simple to live doing art because the market crisis, so we also do different "things" like to teach art in our lab (my hubby) and, for me, to create something more commercial (and less expensive for buyers) to sell.
