Teaching Up: What Mentoring Juniors Teaches You

Mentoring is usually framed as something you do for someone else — a generous act of passing on what you know to those coming up behind you. It is that, but it is also one of the most underrated ways to improve your own practice. Teaching juniors forces you to examine, articulate, and defend what you do, and in the process it sharpens you in ways that solitary experience never could. The surgeon who teaches well almost always becomes a better surgeon for it.

Teaching forces you to understand, not just to do

Much of a surgeon's knowledge is tacit — felt in the hands, sensed in the moment, never fully put into words. The instant you have to teach it, you have to make it explicit, and that act of articulation reveals what you genuinely understand and what you merely do by habit. Explaining a decision to a trainee, and answering their "but why?", exposes gaps in your own reasoning you did not know were there. Teaching is one of the most effective ways to discover, and then close, those gaps.

Questions from juniors keep you honest

Trainees ask the questions that experienced surgeons stop asking themselves — the naive, fundamental "why do we do it this way?" that long familiarity has buried. These questions are a gift. They force you to justify practices you had stopped examining, and sometimes to realise you cannot, which is exactly when learning happens. A junior who asks why keeps you intellectually honest and prevents the quiet ossification that comes from doing things the same way for years without re-examining them.

Watching others learn shows you your own blind spots

When you teach, you see your craft reflected in someone else's struggle to acquire it, and that reflection is illuminating. The steps a trainee finds hard, the errors they make, the things they misunderstand — these often map onto subtleties you had stopped noticing in yourself. Observing the learning process from the outside reveals the structure of a skill in a way that performing it never does, and that clearer understanding flows back into your own practice and your ability to teach it better next time.

Mentoring builds the judgement to lead

Helping someone else develop requires patience, the ability to give feedback well, and the judgement to know when to guide and when to let them struggle safely — all skills that transfer directly to leadership. Mentoring is, in effect, leadership practice on a small scale: you are responsible for someone's growth and safety at once. The surgeons who become good leaders are very often those who learned, through mentoring, how to develop other people and bring out their best.

What you give comes back

There is a quiet return on generous mentoring that goes beyond the personal satisfaction of it. The trainees you invest in become colleagues, allies, and eventually peers who remember who helped them. The reputation of someone who develops others well is valuable in itself. And the act of giving — of contributing to the next generation rather than merely extracting from your own career — is, for many surgeons, among the most meaningful parts of the work.

Mentoring juniors is genuinely generous, but it is far from one-directional. It forces you to understand your own craft, keeps you honest through the questions only beginners ask, reveals your blind spots, builds the judgement to lead, and returns more than it costs. Teaching up is one of the best investments a surgeon can make — in others, and, almost incidentally, in themselves.
