A few thoughts, as someone who went from being deathly afraid of talking in front of the class in Junior High School, to presenting well over 100 times:
- Just do it: Find opportunities to talk in front of people. Come up with things you know about, and find meetups or similar, and talk. Part of it is just getting familiar with it.
- Watch other people do it: Find other presentations that have lots of views and/or that you enjoy watching, and figure out what you like about them. Then try to do a similar thing.
- Figure out what you want to say: I've spent a lot of time talking impromptu. The talks I like the most, and the feedback I've gotten, has been refine your message and practice your presentation and pacing. The best talks I've seen really had their message refined.
