When i read your post i feel the struggle. Its not for me to judge if you make a wise decision or not.
When you a looking for a niche to excel in is imho already doubtful, i believe when you explore and try out different things you will find the niche or not which truly resonate with you. The first and foremost thing should be that you love doing it, when you get energy from doing it the journey and growth will come. And even it does not its something you like doing than it does not feel like a job.
I hope you are not financial depended to find your passion else it can become a burden.🙏
I have been trying to make it a sideways passive earnings. luckily not depending on it solely so far. I am not sure, I would be able to make it or not. What if you were in this situations, what steps would you have taken to make it a success? I love playing games, sometimes record and post at socials also, but finding it hard to develop a strong community who can support. yes, i enjoy it but that's not the end goal. There is something missing, i am not able to understand, i think so. 😅
That is good so you have time to explore.
What is make it or not, that is purely for you to decide. Do you want your own community or be part of one. There are plenty communities where you could be part of. Join the discussions and share you opinion / blogs / videos. This takes time, even years imho. If you want to make videos about something join a community that make video ask tips on that or other skills presenting or writing.
When you want to create your own community that is freaking hard if you asked me. you need to have a lot a different skills... But there are plenty of persons doing it, often you only see the end product not how they started, keep that in mind.
