From good to bad this week – but nothing unplanned. A business trip, followed by a week’s training (with evening group work) left zero time for PhD. Next week is another work trip – this time to London. I will take a few days after including a weekend to get some serious work done. I managed to get access (24 hours) to the library at my old university. I should be able to spend some quality catch-up time if I stay behind after the meetings.
