How to perform better in a PhD program There may be times that we choose to go to PhD programs. If there are several good advice offered by the PhD that may contribute to a successful pathway towards success. First of all, being prepared. Guo himself spent 2 years in MIT as a graduate student before he went to the CS PhD program. As he said in this book, 2 years of graduate training offered him with solid programming skills and enabled him to quickly adapt to the research environment. To most students who prepare applying for a graduate school, it is important for them to equip themselves with strong writing skills and substantial capabilities of summarizing materials from diverse sources. Moreover, the PhD applicants, whatever fields they are applying to, should be able to write decent, concise emails. In this book, Guo cold-mailed to several professors and gained decent outcomes. It is necessary for everybody to learn how to write e-mails which are polite and moreover, interesting enough for others to reply. Next, know when to exit. Guo spent his first and third year doing Klee projects. After failing for several times, realizing that he was probably not able to give out a decent paper, he exited. The decision was essentially important. It would be never possible for Guo to graduate if he continued with the Klee project. And, as for us, we should have to ability to assess ourselves when we do certain things. When we choose a course, we should have in mind whether we are able to achieve the course requirements. Furthermore, we should not limit this when choosing courses or doing projects. We should be able know what our long-term choices are and do things that pave pathways towards that goal.
