I discovered early on when learning to oil paint that applying background color was important to forming a complete painting. That discovery was true even when the underlying paint could not be consciously seen– somehow the background color comes through. A similar phenomena is true for influencing others, whether it’s during a casual conversation or public speaking with a large audience. When talking on a subject, it’s the in-depth understanding of a topic which offers a real chance to influence others. And, the things that go unsaid (the background paint) is just as powerful as that which is spoken.
