1) Value people and let them know it. Be creative with the communication you have with those whom you respect and appreciate. Start by saying so, then be creative and buy or make them a gift, ensure you praise the person in front of others, always be genuine and sincere.
2) Learn to listen, so often we are thinking about the next thing to say, stay focused and open minded and give them clear eye contact and don't interrupt.
3) Believe and live what you communicate, it's important that we walk the walk and live a life of integrity and credibility, we are all being watched, whatever you talk about, understand it and believe in what you are saying, don't share empty words which have no power or energy in your life.
4) Master communication skills, read books, go on courses, listen, ask for feedback, be intentional.
