How to avoid bias and the vicious circle of being a solopreneur?

Hi everyone, I hope you're well (and happy new year!).

I wanna ask how you manage to be a "Solopreneur" and to do all by yourselves, avoiding a vicious circle and bias.

At least in my experience, I've been doing almost all the processes from ideation, prototyping, building, and testing for my side hustle (that became the primary objective last month). As I started with a poor MVP (no shame on that), the beginning was easy to manage (I'm not a developer, but I started learning Ruby on Rails since that day and hired some freelancers for the hard and specific stuff), but as the months go by the tests had become more and more complex, the ideation started to have lots of spin-offs and sometimes I feel overwhelmed by the ideas and paths to go (I have some sort of prioritization, but I think that leads me to the same problem I started on this post - there's probably lots of bias on that).

Some problems/doubts that I have related to this topic:

-- I'm so immersed in the product, as I know all the data and details, that it became hard for me to simply explain the product (every phrase has a topic about doubt or idea, and every test that I mention lacks something that I want to explain, etc...). Do you have some framework to help with that? I thought about creating a presentation for my parents - as they are elderly and don't understand much about technology, seems like a good exercise to resume - and also some friends - almost no one in the tech field, so will be easier than my parents but also a challenge to summarize.

-- I have some friends and ex-coworkers that know that I'm building the product, but no one has time to go deep on a conversation about this periodically (I have lots of sporadic talks with them, telling about the news and milestones, but as they are not immersed on data, I feel the discussions are mostly superficial in some way). Have you done some kind of "board" that knows about what you're creating and helps to discuss important themes (even if it's private with you and asynchronous)?

Hope it helps (me and others that find the post) to find a better way to manage this journey. If you want to know (and follow) to know more of what's happening (and some of my philosopher's doubts) about my product, here's the link to the profile:
