I hope to see myself stand before a large number of people,giving them words of advice,encouraging them and provoking them to act positively. But i don't know howw to go about it.

I don't wht group to join and the necessary steps to take,

I believe i've got the imperative prowess for this tasks,pls if you have an idea on how to go about this,hit me up.

what is difficult about this? you surely can give words of advice to a single person. right? the only thing you have to do is consider the large crowd as though you are talking to a single human and speak with that same courge. Do not pay attention to the numerous eyes and those faces that look disapproving. just focus on your speech.
