Let's say for example (just an example)
A person was told at a much younger age,''I think you'll make a great teacher someday.'' And then the person kept thinking about it.
One day, that person became a really well skilled teacher.
How do you know if that's what the person truly wants or it's more of a catalyst by a self fulfilling prophecy?
It's an interesting sociological/human nature issue to think about.
