So if you had to classify yourself, which camp would you place yourself in: introvert  or extravert? 

If you have placed yourself in the introvert camp, then  understanding the importance of public speaking and becoming an  effective public speaker is going to be that much harder for you to do.  

However, the good news is that if you can understand the challenges that  you’ll be facing as an introvert, then you can take steps to overcome  them and become a world-class public speaker.
