Streaming frequently, I.e. not once in a blue moon or something. I personally disagree. You should stream what you want, when you want in my book. It's not about the numbers, it's about enjoying it.
be enthusiastic, dont be boring and monotone like some TSW streamers (not naming names|) come up with fresh new ideas, be engaging with the audience.
Got any ideas just go to my twitch channel and post them. My twitch channel is https://www.twitch.tv/abstractartist3981
