This inspiring. Keep it up and good luck! I like working in startups too and live well below my means. Have had about the same cadence as you re: being out of work. I have a dependent so my calculus is a little different, but similar on par.
My non-startup friends do not understand. They're always this funny mix of confused, worried, and jealous when I take a break, but I've never had an interview for a startup job where anyone cared about any gaps in my resume.
