Different people have different expertise and weaknesses. Now, we will talk about public speaking where some people are having a hard time.
A person who is shy and introvert in nature will find it really hard. Crowd is the main enemy and talking is such a burden to them.
But whether we like it or not, we will encounter it and need to face it. The main purpose of public communication is to communicate clearly with efficiency.
If we want to improve it: we need to be specific with our purpose in public speaking; talk for the audience and not for yourself;help the audience to understand you; don't give so many information as it will not help the audience to understand;constant practice and have confidence.
Speak as it was nothing. You'll fill freedom.
I actually not good in public speaking but i hope i could make it in the future
