How can something be new, and be improved at the same time? Either it's something new, that was never there before. Or it's improved version of something that already existed.
Anyway, I'm improving my presentation skills, and I'm able to stand in front of whole class and talk without fear or nervousness. I'm able to not blindly read the slides, but explain to the class, looking in their eyes, what information I'm presenting. I'm able to get myself be fully involved in the presentation and enjoy the fact that I have the privilege to have people listening to me.
Yea I still suck according to standards required, but it's better than before ;)
