First-year PhD students in physics are advised to maintain focus on their research by avoiding unrelated jobs, as divided attention can hinder progress. Choosing the right supervisor and project is crucial; students should seek mentors whose styles align with their learning preferences and select projects that ignite their passion while developing necessary skills. Establishing clear expectations with supervisors regarding meetings and project milestones is essential for success. Maintaining a balanced life is emphasized, including proper sleep, nutrition, exercise, and social interactions, to prevent burnout. Early writing and extensive reading in both the specific subfield and broader areas are recommended to enhance understanding and creativity. Students should also prepare a backup plan for potential non-academic careers, considering how to market themselves and what skills to acquire. Overall, proactive engagement and effective time management are key to thriving in a PhD program.
