How much of the year is left Friday, December 1, 2017 December 1st. ~8% of the logbook still empty. 31 days left in the year. If you started tomorrow, you start a 30-day challenge. Or, you could go for a walk. Or tidy up. Or just chill. (Lord knows we all need to.) As ever, the question is the same: What will you do with your days?
