I know you're looking for attention or validation, but I have a feeling you'll probably get more negative attention than positive when you seem to be equating having $1M in liquid assets to "starting with no income, no product, no business".
But domain knowledge and contacts will probably be the biggest assets OP turns out to possess. Don’t undersell those.
And 80k is still well over the average household income
Getting a sustainable business is not easy. Lots of groups don’t get there with $10’s of millions in venture capital. So from a business prospective he is starting with nothing but does have a personal safety cushion.
What I think you mean is you don't have steady W2 income from an employer.
A different post would inspire me to try too. A post like this one makes me sad to be less privileged.
And I'm not saying that to make you feel bad or anything. People have different circumstances and make different choices for themselves, some biased by the circumstances and some not. I'm just saying it as a consumer of a text. Just throwing my opinion with no expectations of anyone catching it.
Depending on where you live, who you support (or are supported by), and how capital intensive your independent business is, that could be plenty. Plus, you've already got a book deal worked into the business plan it seems.
