TJ Walker's YouTube channel offers tips to improve how you come off in front of a crowd. The channel is run by its namesake, who is CEO of Media Training Worldwide. According to his personal website, since 1984 Walker has trained heads of state, Nobel Peace Prize winners, Super Bowl champions, and other prominent figures to appear in front of cameras and crowds.
Although the channel's videos don't exactly boast Hollywood-quality production, there are a lot of them (more than 1,900), and they cover a wide variety of practical topics. These range from timeless essentials—for example, mastering your body language, eliminating verbal ticks (such as like or um), and remembering your lines—to ideas that have found relevance in the modern world, such as looking your best on video calls.
One interesting aspect of this channel is that Walker will sometimes create videos in response to his viewers' questions. In the intro video on his channel's homepage, Walker implores viewers to leave any questions as comments to the channel's videos and check back frequently to find an answer.
