Balance

If you pay attention to spreading one color in a balanced way around the canvas, you don't run the risk of getting stuck in the details - a true pitfall. You're also then a lot more cognizant of the type of stroke you're making - for me it's the short horizontal slab with a palette knife that brings the most satisfaction, especially when there's sufficient color that your edge can examine their relationships. Another element that adds to the sameness of texture is s the tool you use, that is staying with same palette knife or brush if repetition is desired, or switching it to a thin outline with a tiny yet bold brush line. I'm certainly a descendant of Russian painters (Kandinsky, Chagall, Rothko), string  the bold black outline is very important to me after all, especially when it's a jagged dancing stroke that seems to resemble a sting. The appearance of this pulsating string seems to be more importance than simply the color relationships. Pay close attention to the palette you're mixing on for pleasing color combinations - this might be the best guide for your painting's progress if nothing else. And know when you get tired in order to stop before it's too late.
