Youtube is more useful than it appears! I watch a lot of beauty gurus (and their vlog channels) but also Kingsley for laughs and The Readables for book reviews. Either way, they're all entertaining and good for passing the time, which is what I ultimately use youtube for.
I usually go on Youtube for makeup tutorials. I love makeup and still learning the basics, tips and tricks on getting that flawless look/ i also go on Youtube to learn how to cook and watch music videos.
