"Do three hours' work a day. It's much better to work on your PhD for three hours every day, than to do nothing one day and nine hours' work the next."
This is the word of God.*
[All: Praise be to God.]
*[The God = an important figure at the Graduate School, whose talks on motivation have helped me peel myself off the floor, and find a new reason to live. On this blog there are several 'Gurus', but only one God.]
