Self-talk is internal dialog that happens inside us. Self-talk always happens when we interact with the environment. Self-talk serves as a bridge between the world inside and outside of ourselves. Everyone always do self-talk, whether consciously or unconsciously. Deepak Chopra, in one of his books, said that everyday we talk for about 55.000-65.000 times with ourselves.
Actually, self-talk is action that we do to interpret an event. Self-talk reflects our rule. Rule comes from belief. Belief supports value.
In other words, if we often observe our self-talk, we can learn a lot about our belief system.
The best time to observe and analyze our self-talk is when our emotion flare, or when we experience the intense emotion. This emotion is the result from interpretation. Interpretation comes from our belief.
