TJ Walker (from a livestream titled "THE HABIT INFLUENCER - Personal Development") explains how to consistently improve public speaking: practice frequently by accepting every speaking opportunity; always ask for concrete feedback (ask what listeners remembered, what to repeat or avoid); and study a range of role models — including speakers you disagree with — to learn techniques and expand your toolkit.

How do you consistently get better as a speaker? How do you not be one of these people who sort of plateaus, you get to a B plus level, but you're like that for the next 30 years. It's like a lot of skills in life. People who take one golf lesson once and golf once a year typically don't get that much better. People who take golf lessons and play golf and they do both of those each week, usually make some progress. Now, they might not get to the professional level, but they get better further along than someone who just does the golf once a year. Same thing with public speaking. For starters, look for every opportunity you can to speak. Don't turn down speaking opportunities. Next, always ask for feedback. Don't just ask someone what did you think? Ask them, what did you remember from my speech, my presentation, what did you take away, really listen? Try to figure out what I do well in this presentation so I can use it in the next presentation. What didn't work that I tried, so I'm not going to use it next time. And then look for your own public speaking role models. Watch TED talks, watch YouTube, look at other speakers. Whether you love sports or the arts or politics. Look for people that, that you like and respect and learn from them. But also do the opposite. Look for people you don't respect, but you know they're good speakers. And analyze what they do. So look for a talk radio host who has a political opinions the exact opposite of yours. Force yourself to listen to that person five minutes a week. You'll learn a lot about good communication. Find someone who is preaching a religion that is not your religion. You don't agree with what they're saying, but listen to them one day. Tv, radio. Analyze what they're doing not so that you'll copy them, but so that you can learn from them and expand on your own toolkit of public speaking. Do that, do that consistently and you'll get better and better as a speaker.
