It's nearly the end of a long week, busy and half of it spent in hotels. My Fitbit tells me that recently I've averaged less than 6 hours sleep per night, compounded by deadlines at work (exciting things admittedly), a house renovation and a new kitten. In the gym I'm finding it harder to hit my goals, but what about work? Cognitively am I missing goals without realising? This article suggests I might.
