The relationship you build with a junior colleague this year rarely feels like a career decision. Ten years later, it sometimes turns out to have been one of the most consequential ones you made.
What the research says
Cal Newport's So Good They Can't Ignore You makes the case for what he calls career capital, rare and valuable skills that function like financial capital, compounding slowly and mostly invisibly until they suddenly do not. Newport is a working computer scientist, though his academic publishing is in distributed algorithms rather than careers, and the book is built from interviews and case narratives rather than a research programme. The argument is that this capital comes from deliberate skill-building, not from chasing what feels urgent or passionate in the moment.
Why the decade-scale decisions rarely feel urgent
A quarterly deadline announces itself. A decade-scale investment, a skill built in a role that felt like a detour, a relationship maintained with someone junior who later became senior, does not. Nothing about either one feels pressing on the day it happens, which is exactly why they are the easiest kind of investment to skip in favor of whatever is actually due this week.
Where to start
Once a quarter, ask yourself plainly what you did in the last three months that will still matter in ten years, separate from what got done on time. If the honest answer is nothing, that is worth noticing, not as a failure, but as a prompt to protect a small amount of time for the kind of effort that does not show up on this week's list.
Knowing which specific skill or relationship is actually worth that long-term investment, versus what just feels like it should be, is a judgment only you can make for your own field and trajectory. What this gives you is the habit of asking the question at all, since it is easy to let an entire year pass without it.
There is a specific way to identify which of your current skills already has real compounding value, and it is worth working through properly rather than guessing.
