I highly recommend Toastmasters. Best place to practice giving a speech in front of a group of people that you don't know. They have chapters all around the world.
Had great fun with them when I was 16 years old. They brought us to the pub for a few drinks. The good old days.
Feels like a cult, never heard a bad thing about them.
Just my internal guts feeling that probably is wrong.
Yeah, agreed. But it also gets you comfortable presenting, I was recommended them by a trusted friend as well. The overtly marketing hype on their website reminds me of those motivational speaker cults.
They don't take all your money or isolate you from your friends and family. If it's a cult, it's of the harmless variety.
Be alert for any recommendations to sound more certain than you are.
