Advice please

The issue:

I want to create streams of income but the issue is I am overwhelmed by the options I have.

I do freelance SEO (write content too sometimes) for reputable brands in the US. Mostly e-com, b2c and local.

I've ranked alot of sites in the last 7 years. This means I know nitty gritty of alot of niches.

I want to get some passive income from a side business apart from freelancing and have saved some amount to invest.

The issue is that I have seen great numbers and issues with all these businesses and thus feel overwhelmed to which one should I invest my time, effort and money in.

Previously, I had a great idea of detecting ai content and at that time, there was literally no one in market doing it (at the time of chatgpt release) but I lacked technical knowledge and thus the developer/programmer scammed me while creating the software.

I've not started my own business since this happened so I have some fears too.

So, I guess to avoid that, I should partner up with someone this time.

Ps: I want to pivot to my own products rather than turning my freelance into an agency biz. I just want a less stressful business.

Any advice for me?
