Be wary of the words you say. Be careful of the intentions you possess. Be cautious of the steps and the reminiscent. Take a step back, pause a second and feel it. These are the few measures that can improve the way we engage or interact with a second party or in a conference.
I believe that even before the genesis of weapons and tools way back in the beginning of time, speeches are the first weapon ever created.
Through feelings we give off emotions, from motions we let off sounds and from the thoughts we create speeches. From my understanding and personal opinion it is like planting a seed in a person heart.
