Championship rings fit one finger. A changed life fits a whole family.

Achievements sized for one person stay that size. What you do for the people around you spreads outward instead, changing conditions for people who never did the work and will never know what it cost. One is an ornament of a single moment. The other reorganizes what is possible for everyone standing nearby.

When weighing where to put your effort, ask how far the result travels. Both kinds are worth having, and the individual one is easier to measure, which is why it gets chosen by default. Notice when you are choosing it out of habit.
