The longest goals require identities capable of surviving uneventful days.

If your sense of yourself depends on things happening, then long uneventful stretches feel like a crisis of identity rather than a normal phase. What sustains long goals is a self-image that survives ordinary days, one built on what you do rather than on what you achieve.

Ask whether you can feel like yourself on a day where nothing happened. If not, that fragility will end long projects. Anchor the identity to the practice instead of the outcome.
