E-Concussion

My goal is to be a good presenter in front of people.
I have to learn to use English to give my expression to everyone.
I want to practive using alternative vocabularies and phrases even they are rarely used in daily conversation.
That would enlarge my word database so that I am able to speak more frequently.

How to archieve the goal?
I think I will take doing presentation as my method.
And hope that all of you could ask me any kind of questions and discuss with me.
