Starting a PhD: 10 Things I Wish I’d Known

Starting a PhD can feel like arriving late to a conversation in which everyone else understands the rules. They usually do not. Research degrees contain uncertainty by design, and much of the hidden curriculum is learned through experience.

For guidance across the whole doctoral journey, use the PhD & Academic Life hub to find resources on applying, supervision, research, writing and presenting.

This is not another description of what grad school is like. It focuses on the gap between common expectations and the practical reality of beginning a doctorate.

1. You are not expected to know how to do the entire PhD

You need enough preparation to begin, not enough knowledge to have already completed the research. The first year often involves narrowing the question, learning methods, mapping literature and discovering why the original plan needs to change.

Ask what a strong first three months and first year should produce. Concrete milestones are more useful than a vague instruction to “read around the topic.” The PhD timeline for years 1–4 shows how question development, research, writing, submission and viva can fit together without pretending every doctorate follows the same calendar.

2. Uncertainty is part of the job

Research exists because the answer is not known. Supervisors can recognise patterns and prevent avoidable errors, but they will not always know what the data means or which path will work.

This can initially resemble incompetence. It is usually the transition from solving assigned problems to making defensible decisions under uncertainty.

3. Supervision shapes far more than the thesis

Supervisors influence feedback, confidence, opportunities, authorship and whether boundaries are respected. A brilliant researcher is not automatically an effective supervisor.

Agree early on meeting frequency, draft turnaround, communication, leave, data ownership and what to do if either party is unavailable. Keep short written records of important decisions. The supervisor meeting agenda and action record can help you turn each discussion into clear next steps. If you are still applying, see how to assess a PhD supervisor.

4. Administration can become a research risk

Ethics approvals, purchasing, access permissions, payments, visas and progress reviews can delay a project. Learn the institutional process before it becomes urgent and retain copies of approvals, submissions and important emails.

Build administrative lead time into the research plan. “Waiting for approval” is predictable even when the exact delay is not.

5. Workloads are not comparable

A laboratory experiment, archive visit, software project and theoretical thesis impose different rhythms. Funding, teaching, caring responsibilities and supervisor expectations add further variation.

Someone else’s hours tell you very little about whether your work is progressing. Compare your activity with agreed milestones, not with the most visible or exhausted person in the department.

6. Flexibility needs boundaries

A flexible schedule can be valuable, but work without a natural endpoint expands easily. Define working hours where the research allows it, take leave and create a shutdown routine that records the next action before you stop.

Our time-management guide for PhD students provides a practical weekly system.

7. Every opportunity has a cost

Teaching, committees, collaborations and academic conferences can build valuable skills and relationships. They can also fragment the time needed to complete the thesis.

Before agreeing, ask what you will learn, who benefits, how much time it really requires, whether you will be credited or paid, and what planned work will move. “No” and “not this semester” are legitimate answers.

8. Feedback is not a verdict on your ability

A heavily commented draft can be normal, particularly early in the degree. Convert feedback into an action list, identify contradictions and ask which changes matter most.

If comments remain vague, ask specific questions: Is the problem the claim, evidence, structure or explanation? What would a successful revision allow the reader to understand?

9. Isolation is not inevitable, but community requires effort

The thesis may be individual, yet research depends on discussion and criticism. Join a writing group, methods community, journal club or peer check-in. Build relationships outside your immediate supervisory team so one difficult relationship does not become your entire academic world.

10. A PhD does not need to consume your identity

Progress will fluctuate. Experiments fail, chapters are rewritten and comparison can make ordinary setbacks feel personal. Maintain relationships and interests that have nothing to do with the doctorate.

Persistent anxiety, depression, exhaustion or inability to function should not be treated as an unavoidable rite of passage. Use institutional and professional support early. For a difficult writing period, start with our guide to dissertation anxiety and procrastination.

A first-month checklist

• Confirm funding, payroll, enrolment and access.
• Agree on supervision and communication expectations.
• Map formal milestones and approval processes.
• Create a simple literature and note-taking system.
• Identify training that the project genuinely requires.
• Meet peers inside and outside the immediate group.
• Define a sustainable weekly routine.
• Record questions rather than pretending to understand everything.

Questions to ask your supervisor early

• What should I be able to explain or produce by the next milestone?
• How far in advance should I send drafts?
• How are authorship and research ownership handled?
• Which seminars and opportunities are genuinely important?
• Who should I contact when you are unavailable?
• How should we raise concerns about the project or working relationship?

The revision preserves her central observations about supervision, bureaucracy, boundaries and uncertainty while presenting them as transparent lessons rather than universal rules.
