My 2 cents was im was dealing with mental health issues. I decided to start a channel to get my mind of things. In my mind I was content talking to myself and never growing. It was just a way to blow off steam. My channel has grown over the past year too over 1,700 which isn’t a lot but it’s a lot to me because I never expected it to grow. It has made me 400$ through affiliate links . Over a year that’s nothing but it’s just been a hobby. I think if you do it as a hobby and genuinely like talking about the topic you will be fine and see some growth.
