The greatest thing about the challenge is that you have to post a video because you're a part of a community. It was the most difficult thing for me to do — to shoot a video, edit it, and upload it to my channel, but, thanks to the course, I did it. Marina gives all the lifehacks that help video creators, even on a channel with a small number of subscribers, so their videos become viewable. For example, I had 500 views on a video I made during the challenge in only TWO DAYS, and I only had 30 subscribers. This is SO COOL, I am grateful to Marina and this course!
