Handling Broadcasting Jitters

Even though I have loved being a dj in school when i was younger, and have done speeches in front of people and groups, there is still that nervousness that will pop up time to time.
Hell, even in my own life outside of broadcasting, i sometimes have the jitters and need calming down.
Ive tried meditation, cbd oil, breathing exercises, and all have worked in some small way or another.
I have seen quite a bit of success by coming to the conclusion that if you know something , and know it well, as with anything in life, you can bring it out to others very successfully.
