This document discusses the role of a thesis as an academic avatar that represents the author. It notes that 600 years ago, obtaining a PhD required demonstrating knowledge through oral disputations, but that is changing as theses become written texts. An effective thesis acts as an avatar that must "speak" for the author to examiners, as the author is not present. The document provides advice on writing a strong thesis, including making it clear, precise, concise, well-planned and well-edited. It notes examiners may skim read parts of the thesis, so it is important to engage them throughout. The thesis must demonstrate the author's scholarly capabilities and tell a compelling story to convince examiners they would make an interesting future
