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.🙏
