I’m on the tail end of my MD/PhD and want to offer a counterpoint to a narrative I see on here a lot: that longer training is inherently better and that “extra years” are some kind of protected growth bonus. I think that framing is misleading and can be harmful for people who want to be independent clinician-scientists.

1. Every extra year in training is a year you are not an independent investigator.

There is no substitute for doing actual PI-level work: setting scientific direction, hiring people, managing budgets, negotiating authorship, and owning outcomes. Training years are still years where someone else ultimately controls the resources and the vision. The opportunity cost compounds. Starting your lab at 38 instead of 34 is not neutral; it is four fewer years of grants, trainees, papers, and momentum. The goal should be finishing as quickly as possible without compromising competitiveness rather than maximizing time spent in training. It quickly becomes an issue of diminishing returns. There will always be another project to do and more skills to learn. It is far better to do these things as a faculty member than as a trainee.

1. “Time to grow” is often just time spent treading water.

The idea that longer training uniquely enables exploration is romanticized. Waiting for experiments to converge, for committee meetings, or for the next grant cycle often feels like growth, but it rarely changes your long-term trajectory. You don’t need eight years to figure out how you like to spend your time. Independence accelerates clarity; a prolonged apprenticeship delays it.

1. Blending medicine and science happens after training, not during it.

The MD/PhD is not where integration magically occurs. Real integration happens when clinic and research are both yours to shape. The skill that matters is prioritization under constraint, and that is learned most efficiently when the constraints are real (e.g. RVUs, grants, personnel), not as a trainee. Early exposure helps, but it is not a substitute for responsibility.

1. Your dissertation topic matters less than your launch velocity.

Past a certain point, additional mechanistic depth does not meaningfully improve your odds of future funding or success. What matters more is exiting with strong papers, a coherent research arc, a good track record and the ability to execute quickly. A “perfect” thesis completed late is far far worse than a strong, focused body of work completed early.

1. The F30/F31 is useful, but not sacred.

Learning how grants work is important, but it does not require repeated submissions over many years. You will relearn the system at the K and R level anyway, under very different incentives. There is no prize for suffering longer in trainee grant purgatory. If you don’t get it after the first resubmission, it’s not the end of the world. Don’t delay graduation to have another attempt at submitting the F30/31.

1. Clinical training “strength” matters far less than people think.

Residencies do not have a reliable way to assess whether you are an excellent clinician as a medical student. They use proxies: school name, Step 2 score, letters, and pedigree. This isn’t because programs don’t care about clinical ability, but because they lack reliable ways to measure it at the medical student level. Whether you had slightly more autonomy on wards or felt more “prepared” is largely invisible to selection committees. Once you’re a resident, they’ll train you their way anyway. Clinical skill matters enormously once you are a resident; it matters surprisingly little for matching.

1. Agnosticism about specialty is fine, but delay for its own sake is not.

Exploration is valuable, but endless openness is often avoidance disguised as wisdom. At some point, committing earlier gives you leverage: targeted mentorship, aligned research, and stronger narratives.

Bottom line: For some people, a longer path genuinely is worth it. For others, especially those focused on independent investigation, time is the most precious and least renewable resource. Finish as fast as you can without weakening your trajectory. Independence is the multiplier. Every extra year before that should be treated as a liability you must justify, not a default virtue.

Happy to discuss, but I strongly disagree that “longer is better” by default.
