Simple....
A few good ways to talk about yourself--->>>
To mention a few things...you could talk about your personality, your hobbies, what kind of a person you are (charismatic, intriguing), what you love to eat, your family, just you in general; don't be shy...it's you you're talking about, and you know yourself more than anyone else!
Thus, your answer.
An effective way to improve your ability to communicate is to A) be aware of when you are the receiver and when you are the sender.
It is very important to distinguish between these two things so as to achieve a good communication with somebody.
I'm pretty sure it's the Revolutionary Period.
