If you like art or music, think about how you could use that in your streaming to help yourself stand out over other indies.As an indie vtuber let me tell you its so fucking hard to think of stuff you can do that isnt just chatting and streaming a video game. I don't have the push from a manager or the funds to do projects. Its hard to reach out to others because they never get back to your DMs thanks to their menhera or they just have to juggle a shit ton of other DMs.
Then your time is split up for prepping streams, dealing with your community, irl stuff (work, school, family, chores) other things you do like art or music, hanging out with friends and sleeping. it doesn't sound like a lot but some how I feel like a need another me to deal with things and keep track of what's going on. God help you if your health gets in the way. I feel bad every time i have to call off a stream because of sickness.
Fuck man I want to do cool stupid stuff but its hard to find the time to get ideas than put them together.
Let's say you have a subgenre of music you like. Maybe you could do a stream about the history of your preferred subgenre, discussing important works and events. Maybe you could hit up some creator communities and say you want to try some stuff on-stream and comment on it, and see if creators might be interested. If you are more interested in particular bands or musicians, do an overview of the history of that band or musician and maybe listen to some excerpts from their stuff.
Streams that require research do require a lot of prep time, so that's when you can do more casual gaming/chatting streams that require no prep time while you're doing your work.
Hope this gives you a few ideas. Good luck with the grind.
