Most Of What You Learn Will Not Come From Training

Courses are useful and limited. The real curriculum is the work itself, if you let it be.

Formal training does a specific job well. It gives you vocabulary, structure, and a shared reference point with other people who have done the same course. What it cannot do is teach you judgement, because judgement is built from consequences and a course has none. You will learn more about scoping from one project that ran over than from any amount of instruction about scoping, provided you actually look at why it ran over instead of filing it under bad luck. The looking is the part that gets skipped, which is why some people accumulate twenty years of experience and others accumulate one year twenty times.

Making the work teach you requires only a small deliberate habit. After anything substantial finishes, spend twenty minutes on three questions: what did I expect, what actually happened, and where exactly did those diverge? Write the answers down, briefly, for yourself. The value is not in the document. It is in being forced to state your expectation in retrospect, which is uncomfortable and clarifying, and in noticing patterns across a year that are invisible at the level of individual events. Almost nobody does this, and the people who do it are visibly better at anticipating things within a couple of years.

The other engine is exposure to work slightly beyond your current competence, with someone experienced close enough to catch the serious errors. That combination is rarer than it sounds and worth asking for directly. Ask to sit in on the thing you do not understand. Ask to draft the piece that will be reviewed heavily. Volunteering for work you can already do comfortably is pleasant and teaches you nothing, and a long run of comfortable work is one of the quieter ways a career narrows without anyone deciding that it should.
