This is another photo from the 50k in Creede, Colorado. You can easily see the trail in the middle of the photo. You can’t see the trail to the far left and rather than fading into the distance, the trail disappears over a small hill. Despite not seeing it, our minds create an image of what the trail should look like before and after what we can actually see.
Sometimes it works the same way in our daily journey. Even when we can’t see exactly what is ahead, we fill in the details in our mind. Which can lead to unrealistic expectations. Or pleasant surprises.
