It's far better to take a college public speaking class or join Toastmasters, but I'm pretty sure no one ever takes that advice.
......people go from bumbling retard to comfortably speaking to a large group (24) and being able to take questions.....
Definitely do this if you struggle speaking to women...
I didn't take a class, but drifted into public speaking through a hobby....
I was always a bumbling mess around women... Then in my early 40s, I stepped in as the speaker at my local hobby club (Astronomy) when the pre-booked speaker called off at the last-minute.
It helped that I already knew everybody in the room that night, and had a strong grasp on the subject matter.
It went well... word got round and I was booked to speak at other clubs... and it just kinda snowballed - These days I have a whole bunch of astronomy-related presentations ready to go - got two booked to do in January....
It's amazing what it does for your confidence, standing in front of a room full of people on a regular basis - I can now talk to anyone, any time... about anything...
Doing it regularly I soon learned to realise when women were taking an interest (And yes, I've taken advantage of it a number of times)
I can now easily spark up a conversation with any woman I'm interested in... can pick up on her level of interest... and get contact details when relevant.
If she deosn't seem interested, or available, I'll simply not push the interaction, and just go about my day - no harm done...
