My best advice is:
1) Define your channel. Make sure your content is consistent with a purpose. That way those who come by know what they are going to get. People appreciate knowing they are coming to your channel for a known quantity.
2) Choose content you love. Make sure you are covering stuff you truly enjoy. Don’t just do something because it’s popular, do it because it means something to you. When you do that, people will stay with you because your thoughts, opinions, and discussions are genuine. That’s what defines all our channels from the shills: we care about what we cover.
3) Engage with your subs. Build those connections with your subs, especially those first few who jump on board and want to talk with you about your content.
4) Ignore the trolls. No matter how innocent and non controversial you might think what you are doing is, there are always gonna be weirdo SJW and Stan trolls who will find something wrong. If you don’t wanna fence with them and play with them like the retards that they are, then just ignore them and remember they’re the creeps who are obsessing over you for no reason. Just keep doing your thing and only care about what your actual subs want.
