Speak right and speak tight

Lot of us face what Afridi has faced. Some frequently and some less frequently. That is having 'your foot in your mouth'. 
The ability to speak right and speak tight is a real uphill task! We all love listening to ourselves and if we have an audience...wow! Well, some of us just cannot stop preening. Such human beings are quite common and they end up with a greater share of misery in terms of controversies and irate acquaintances.
I believe such entities require a great degree of training in effective communication. How to speak, when and where to say what. The art of communication is actually a science. The methodology studies the human mind and its perception and reactions to situations.
The communication training models are accordingly developed, to suit individual requirements.
For, effective communication is 20% what you know and 80% how you feel about what you know. - Jim Rohn
