Work hard/ Stay clever

We have a weekly online seminar as part of our Master's programme which can be a little hit & miss depending on the enthusiasm of the students.

Our tutor seems buoyed by this and today broke the usual formality by signing off with the words
"Work hard
Stay clever"
Simple yet somehow very motivating - so I thought I'd make it my blip. As the text in the seminar room is not easy on the eye I decided to paint it and snap it while the paint was still wet...
