To be honest, I don't know either, but I think if you understand the basics of marketing and you're constantly doing whatever you do BUT also improving at it regardless of status results, marketing will get easier and easier because 2 things: 1) Your content will be higher quality and more eye-catching and will hook viewers' interest to the rest of your content, and 2) You're constantly getting more eyeballs with every piece of content you create and people will start talking about it and it just kinda starts going more viral over time. The key is to do what you enjoy, but also provide value to people - that's the ultimate rule, don't focus on numbers so much, focus on the long term fulfillment of what you do and results will come.
