Fixed or Flexible? Painting

Painters are supposed to have a specific signature style. But why restricting yourself to painting in one certain way only? Do you not risk becoming a formula and painting the same painting for the rest of your life? Minimalism and maximalism, line and sfumato, hippy and zen, expressive and romantic, feeling and thought, science and art, Jekyll and Hyde. They are all in me, and they all come out at one time or another. My style is to have more than one style. The only difficulty is knowing when to stop.
