Talent gets a head start. Curiosity gets the whole marathon.

A head start matters most at the beginning and least over time. Natural aptitude carries you through the early stages without much effort, which is precisely its risk, since you never learn to work when working is not required. Curiosity keeps supplying reasons to continue long after the novelty has gone, and who is still going in year five decides the distance.

Stop measuring yourself against people who found it easy at the start. Ask instead what would keep you interested in this for a decade. Feed that, because it is the part that carries you.
