I made more money per month as a 17 yo at the end of the dotcom boom than I did the decade after...

But back to the advice: don't sell your house... Get a less demanding job, even 4 days a week, and side hustle the project.

Also considering finishing your degree as a hedge (assuming it doesn't cost too much, I guess it does in the USA).

Yes, started volunteering at 16, got an offer soon and went fulltime. Dropped out of university. At some time I was working on two jobs, one part time of course, and did some freelance while still working full time.

And owning a house. Are you sure you're owning the house, not the bank?
