What an interesting question presenting for me another question. Do I think too much about too many things and only a tad of all those are experienced? hmmmmm . . . I think (There is that word) when we focus on a destination through visualization we do seek that outcome, however the horizon is always changing therefore the journey itself is the adventure.
Keeping focus on the destination, which is an intrinsic value, is important, yet navigating the course to the horizon, which is an extrinsic value, has to occur. Many do not share that portion of visualization as a technique for goal achievement and the changes needed to stay on course. That kinda' is what will mold the person seeking the destination thus the person does change, which means something will be left behind. At task may be realization of what is risked, what is being invested seeking something greater, and importantly acceptance of those outcomes.
I seem to be wandering trying to answer the question as it is a very big question indeed.
