Effective communication is important for sharing information, motivating others, and building relationships. Verbal communication accounts for only 8% of the message conveyed, while vocal tones make up 37% and body language 55%. Poor communication can result from not listening well, having preconceived ideas, or a lack of clarity. It causes issues like lower productivity, mistakes, and damaged relationships. Basic principles of good communication include understanding that everything we do communicates, the way a message is delivered impacts how it is received, and communication is reciprocal. Giving and receiving information respectfully through clear, concise messages and active listening are keys to effective communication.
