I don't think people think that deep as it is all about material things. I know I don't want to be in this country but have no clue where and how that will pan out. Moving forward is the only way and whilst that happens goal posts seem to move at the same pace. Most likely it is your needs and wants changing as you move forward a bit like the majority upping the standard of living as their income increases.
I know my goals and they haven't changed over the last 3 or 4 years and it is the thing that keeps me moving forward every day.
