The human voice and the power of speaking.

 The human voice has been proven to be one of the most inspiring things ever, the amount of speeches that were given during wars, ceremonies, toasts etc. and the amount of people who were inspired by those are a “big confirmation”.

Even though speeches are a common thing, not every human being can perform it in a way which has been done in history many times. Before giving an inspirational speech which in your opinion should change something. You should be sure of the fact that you are somehow known by people or at least respected, that way people know that you can be trusted or that there is a point in listening to your speech.
Wars have been won but also lost because of inspirational speeches.
Let’s pretend that a known trusted person gives an inspirational speech for a war, the speech succeeds but the war is lost, lots of casualties and people who lost their hope in the person who gave the speech. Hatred comes from everywhere, which is deserved, since the person who gave the speech is accountable for what happened.
 The human voice is very powerful and what I just brought as an example is a big proof of the fact that you should think about all of the ways that the situation could turn into before speaking, because your voice can not only hurt you but it can also hurt other people simultaneously.
