There is a saying that if you get something for free, you should know that you're the product. It was never more true than in the case of Facebook and Gmail and YouTube. You get free social-media services, and you get free funny cat videos. In exchange, you give up the most valuable asset you have, which is your personal data.
A lot of people think YouTube is quite easy, when it just isn't. I've been doing YouTube for six years now, and I'd say the hardest years were definitely the first three or four. You have to constantly put out content that is good just to make people come back to your channel, and I work every single day just to try and expand my brand.
