Since I started my PhD studies at Oxford, the full moon has always been my perennial marker of time. How many more full moons will it take to complete the final lap of this marathon? Not many, I hope. This educational voyage has been undulating, certainly not suitable for the hurried and impatient, but I’ve never forgotten the adage that lessons are learnt during the journey, not at the destination. I have begun to understand that a PhD education is more than learning a subject but to acquire the skills to generate knowledge.
