As artists, we reinvent ourselves all the time. We must stay nimble, agile, and alert. The slightest change of color, let's say of the sun's rising or fading, will change the color scheme on the canvas. Colors become lighter or darker instantaneously. Therefore, we cannot idle. The moment of harmony or capture may be lost. The thought might disappear, and the mood gone. It is important to act upon making art quickly, and decisively.
