What are your tips to become a more comfortable, less nervous public speaker?

If it is possible to both love something dearly and hate it passionately at the same time, that describes my relationship with public speaking. I love it, but I wish I was better at it, was less nervous beforehand, and was able to speak without “umms” and ”aaahs” and losing my train of thought during regular conversations. (After all, every conversation is a form of public speaking in a sense). ┬áIn Episode 10 of Seriously Planning, I’m asking about your public speaking experiences and your advice. You can listen to the episode here. Looking forward to hearing your words of wisdom!
