Counting the cost of a goal in the years it takes

Ambitions are usually priced in effort when they should be priced in time.

When people weigh up a large goal they tend to think about difficulty: how hard it will be, whether they are capable, what it will demand of them. What gets counted much less often is duration, which is the part that actually matters. A goal that takes six years takes six years of your life, and those years are not a resource you were holding in reserve. They were going to be spent regardless, on something. The honest question is not whether the goal is worth the effort but whether those particular years are better spent this way than another way, given that they are the only version of those years you get.

Framed like that, some ambitions look considerably better and some look considerably worse. Something you would enjoy doing for six years is close to free, since you were going to spend the six years anyway and this is a pleasant way to do it. Something you would dislike for six years in exchange for a good outcome afterwards is a genuine trade with a real price, and it might still be worth making, but it should be made knowingly rather than by drifting into it because the goal sounded impressive when you first named it.

It also changes how you think about abandoning things. If the cost is measured in effort already spent, quitting feels like waste. If it is measured in years remaining, quitting is simply the decision not to spend more of them on this. That framing is less emotionally punishing and considerably more accurate, and it tends to produce better decisions in both directions: people persist with things worth persisting with, and stop things they were only continuing out of accumulated momentum.
