“EVERY SUNDAY since I started teaching, I’ve forced myself to go into school to prep materials and set up my classroom. During the week, I’m in the classroom before the sun rises. After a full day of teaching, I tutor my struggling students, make phone calls to parents, scrub desks, and sharpen pencils. Here’s the thing, though: I’m not some uniquely hard-working teacher. In fact, in two years, I’ve never once been the first teacher in the building and only twice have I been the last to leave. I feel truly lucky to work in a school with such dedicated colleagues. However, I wonder how sustainable this lifestyle is.
