Natasha, 32, is a former corporate attorney from Chicago who burned out spectacularly (her words: "I billed 2,800 hours and still lost the case") and moved to Portland to "figure things out." Subbing paid the bills. She covered 12th-grade economics and when the bell rang, not a single student moved. The teacher next door knocked to check if something had happened. Nothing had happened — a discussion about interest rates had gotten so animated that six students legitimately forgot the period had ended. (Economics. Interest rates. Forget the bell. Let that land.) Natasha held an unofficial 15-minute overtime session. No one left. The school has since asked her to run an after-school finance club. She's charging $50/hour. It's full. Waitlist has 11 students.
