The entrepreneur is maybe not too strict on the rent payments? Maybe he adds other housekeeping services that balance the money side? Maybe he sells his body. The longer I think about the wilder it gets. I agree with others that while it is intriguing to read about his last year, the way he finances himself on this low level is missing. Depending on where you live even an income of 200k$ can have you living from paycheck to paycheck. So it is very impressive if he pulls this through but how, teach me.
