While I still was in college, I took some oratory lessons, and it was a cool experience. I’ve never been afraid of speaking in public, but hey! Improving your skills have never been a bad thing. :)
It took me a whole semester to learn new skills, and new ways of making presentations. At the end of the semester I got a certificate of “Professional Speaker” from my college, totally, totally like it! Hope to make some money from it soon.
