Most of us think being confident depends upon what we say. It doesn’t, it depends upon what the other person hears. That’s why clear communication is so important:Speak at a steady and comprehensible pacePractice breathing rhythmically and in time with your speechDon’t undersell what you are saying by using maybe words such as ‘just’, ‘like’ and ‘perhaps’Maintain eye contact at all times, and remember to smile.
