Long-term success often looks unimpressive in real time.

From inside, a successful long-term effort feels like a series of ordinary days with occasional problems. The impressive shape only appears afterwards, when the whole thing can be seen at once. Judging by how it feels in real time will always underrate it.

Stop checking whether this feels like success. It will not, for years. Check whether the inputs are right and let the shape emerge in retrospect, where it is actually visible.
