I had heart to heart talks with my brother, my wife, and Jeff about what course my life and career were taking.
Jeff has taken a great job, and can't contribute as before to the startup. Not knowing what else to do, I considered entering a business plan competition, to follow up on my work with ego.migra.
Steve Blank would say my problem is untested; it may be real for me, but is it real enough such that if we built a solution, would people actually pay me for it? We need to be sure of these issues before we write up a business plan to obtain financing.
I'll continue to explore the problem space of lonely house dads by blogging. When I feel there is a critical mass of content, perhaps after a year, I'll collate and self-publish the whole shebang on Amazon or on another system.
If the experience goes well, and Jeff sticks with his job, I may not start a business - I may just keep writing, because I am really enjoying it.
