The horizon reminds you that seeing an end is not the same as reaching one.

You can see the line where the sky meets the land and you will never arrive there. It moves as you move. Some goals are like that by their nature, and mistaking visibility for reachability is how people spend years walking toward something that was always a direction rather than a destination.

Check whether what you are pursuing is a place or a bearing. If it is a bearing, stop measuring yourself by arrival and start measuring by whether you are still heading that way. That is the only honest scorecard for that kind of pursuit.
